- file_format, header_guards and clang-format benefit from this short list.
- dotnet-format, Python and JS checks don't, but they're only relevant for
  PRs changing a specific set of files, so we skip them when those files
  aren't modified.

The logic to get changed files only works reliably for:
- Pull request events
- Non-force pushed push events

So when force pushing a branch in your fork, or creating a new branch,
it will still scan all files as fallback.

Upgraded CI runner to Ubuntu 22.04 so we get clang-format 14 out of the box,
so we don't need to install a custom version (saves ~15 s). We also cache
the APT dependencies to speed up the build and avoid flaky Ubuntu/Microsoft
repos.

The checkout might be too shallow so the before commit isn't available.
The logic was already written to take this into account (it then generates
an empty 'changed.txt' which falls back to testing everything), but the
error code would still force terminate the job.

Hopefully we can find a way to make the logic work for merge events too in
the future, but for now this is a quick fix.

The file would be one byte (newline) so the check with '-s' failed.

… change

Previously, in CodeTextEditor, `line_spacing` was forgotten to update
when the editor setting property changed.

(cherry picked from commit 23d6225)

This helps to find such classes without digging
through the rest of the class reference.
Editor-only classes can still be found under
your normal "Node" and "Resource" types.

This also fixes a typo and a missed case from the recent platform docs PR.
