This PR improves the release checklist and scripts:
* Check that the release's commit hash is not all-numeric starting with
0 (this can break SemVer, which [required us to release
v4.21.0-rc2](https://github.com/leanprover/lean4/releases/tag/v4.21.0-rc2)).
* Check that projects being bumped to a release tag do not reference
`nightly-testing` anymore.
* Clarify how to create subsequent release candidates if an `-rc1`
already exists.
* Fix typos in the release checklist documentation.
This PR removes the old documentation overview site, as its content has
moved to the main Lean website infrastructure.
This should be merged when the new website section is deployed, after
installing appropriate redirects.
Developer documentation is remaining in Markdown form, but it will no
longer be part of the documentation hosted on the Lean website. Example
code stays here for CI, but it is now rendered via a Verso plugin.
This PR adds some new information to the release checklist,
as well as some new automated checks to help with the release process.

This PR enables the use of the build-time configuration of the Lean
reference manual URL and updates the release checklist to account for
the reference manual.
This is a follow-up to #7240, after the required `stage0` update.
The release process described here uses the same location for the
reference manual for RCs and stable releases. This is for two reasons:
1. The only changes between them should be a modification of the
embedded version string and updates to the final release's release
notes, once those are included.
2. It ensures that a compatible manual is available at the moment that
the new release appears, so any delay getting it deployed won't be
visible to users.
Some downstream repositories require a `bump/v4.X.0` branch to exist for
their integration CI. This PR updates `release_checklist.py` to check
for the existence of these branches, when needed.
This PR updates the release checklist, reflecting changes noted while
@jcommelin has been releasing v4.16.0.

The semantics of `release_notes.py` was slightly confusing. It is meant
to be run a `script/release_notes.py v4.15.0` on the `releases/v4.16.0`
branch. To help, I've changed the usage to `script/release_notes.py
--since v4.15.0`.
This PR updates the commit conventions documentation to describe the new
changelog conventions, and adds brief documentation of integrated
Mathlib CI, with a link for further explanation.
Users have requested toolchain tags on `lean4-cli`, so let's add it to
the release checklist to make sure these get added regularly.
Previously, `lean4-cli` has used more complicated tags, but going
forward we're going to just use the simple `v4.16.0` style tags, with no
repository-specific versioning.

This PR introduces a script that automates checking whether major
downstream repositories have been updated for a new toolchain release.
Sample output:
```
% ./release_checklist.py v4.16.0-rc1
Repository: Batteries
✅ On compatible toolchain (>= v4.16.0-rc1)
✅ Tag v4.16.0-rc1 exists
Repository: lean4checker
✅ On compatible toolchain (>= v4.16.0-rc1)
✅ Tag v4.16.0-rc1 exists
Repository: doc-gen4
✅ On compatible toolchain (>= v4.16.0-rc1)
✅ Tag v4.16.0-rc1 exists
Repository: Verso
❌ Not on target toolchain (needs ≥ v4.16.0-rc1, but main is on leanprover/lean4:v4.15.0)
Repository: ProofWidgets4
✅ On compatible toolchain (>= v4.16.0-rc1)
Repository: Aesop
✅ On compatible toolchain (>= v4.16.0-rc1)
✅ Tag v4.16.0-rc1 exists
Repository: import-graph
✅ On compatible toolchain (>= v4.16.0-rc1)
✅ Tag v4.16.0-rc1 exists
Repository: plausible
✅ On compatible toolchain (>= v4.16.0-rc1)
✅ Tag v4.16.0-rc1 exists
Repository: Mathlib
✅ On compatible toolchain (>= v4.16.0-rc1)
✅ Tag v4.16.0-rc1 exists
Repository: REPL
❌ Not on target toolchain (needs ≥ v4.16.0-rc1, but master is on leanprover/lean4:v4.14.0)

This PR adds a script to automatically generate release notes using the
new `changelog-*` labels and "This PR ..." conventions.
Usage:
```
script/release_notes.py v4.X.0
```
where `v4.X.0` is the **previous** release, i.e. the script will process
all commits *since* that tag.
This makes it reflect how we are writing release notes for 4.9.0,
including how to handle the `releases_drafts` folder and how and when to
update `RELEASES.md`.

The layout algorithm, while somewhat finicky, is (unfortunately)
necessary for C code to interface with lean structures. This adds a
(AFAIK) complete description of the layout algorithm, including a worked
example large enough to make it possible to reconstruct the whole
decision diagram.

Expands on #3971 to do something useful even before the PR enters the
queue:
If stage0 changes are detected in the PR, set the changes-stage0 label
(which
has a tooltip to explain what this entail), and also remove the label if
it no
longer applies.
@semorrison, does this include all the answers to the questions I asked
in our thread? I think so!

This is still WIP: the checklist for release candidates will get
finished as I do the release of `v4.7.0-rc1`.

This PR adds links to some folder references in the docs, making them
easier to navigate.
Please advise if these need to be made to be full URIs rather than
relative paths in order to work correctly with the doc generation
tooling that is in place.
This Github action automatically updates `stage0` on `master` if
`src/stdlib_flags.h` and `stage0/src/stdlib_flags.h`
are out of sync there.
It bypasses the merge queue to be quick, this way, an out-of-date stage0
on on
master should only exist for a few minutes.
Needs access to a _deploy SSH key_ with write permission.
