This PR adds `@[suggest_for]` annotations to Lean, allowing lean to
provide corrections for `.every` or `.some` methods in place of `.all`
or `.any` methods for most default-imported types (arrays, lists,
strings, substrings, and subarrays, and vectors).
Due to the need for stage0 updates for new annotations, the
`suggest_for` annotation itself was introduced in previous PRs: #11367,
#11529, and #11590.
## Example
```
example := "abc".every (! ·.isWhitespace)
```
Error message:
```
Invalid field `every`: The environment does not contain `String.every`, so it is not possible to project the field `every` from an expression
"abc"
of type `String`
Hint: Perhaps you meant `String.all` in place of `String.every`:
.e̵v̵e̵r̵y̵a̲l̲l̲
```
(the hint is added by this PR)
## Additional changes
Adds suggestions that are not currently active but that can be used to
generate autocompletion suggestions in the reference manual:
- `Either` -> `Except` and `Sum`
- `Exception` -> `Except`
- `ℕ` -> `Nat`
- `Nullable` -> `Option`
- `Maybe` -> `Option`
- `Optional` -> `Option`
- `Result` -> `Except`
