feat: Array.insertIdx/eraseIdx take a tactic-provided proof (#6133) 
This PR replaces `Array.feraseIdx` and `Array.insertAt` with
`Array.eraseIdx` and `Array.insertIdx`, both of which take a `Nat`
argument and a tactic-provided proof that it is in bounds. We also have
`eraseIdxIfInBounds` and `insertIdxIfInBounds` which are noops if the
index is out of bounds. We also provide a `Fin` valued version of
`Array.findIdx?`. Together, these quite ergonomically improve the array
indexing safety at a number of places in the compiler/elaborator.

feat: change Array.get to take a Nat and a proof (#6032) 
This PR changes the signature of `Array.get` to take a Nat and a proof,
rather than a `Fin`, for consistency with the rest of the (planned)
Array API. Note that because of bootstrapping issues we can't provide
`get_elem_tactic` as an autoparameter for the proof. As users will
mostly use the `xs[i]` notation provided by `GetElem`, this hopefully
isn't a problem.

We may restore `Fin` based versions, either here or downstream, as
needed, but they won't be the "main" functions.

refactor: remove mkRecursorInfoForKernelRec (#5681) 
it seems to be unused, arguably even for kernel recursors their type
should be usable with `mkRecursorInfo`, and removing this will help
understand the impact of #5679.

refactor: more idiomatic syntax for if h: (#5567) 
https://github.com/leanprover/lean4/pull/5552 introduced a fair number
of `if h:`, but the slightly preferred style is `if h :`, with a space,
so here goes a quick `sed`.

chore: switch obvious cases of array "bang"[]! indexing to rely on hypothesis (#5552) 
Update certain uses of `arr[i]!` to use the "provably correct" version
`arr[i]`, in order to use "best practices".

I currently can't stand `throw_error`, and I am optimistic about
server highlighting feature you are working on :)
