CI/codespell: revert changed-files action removal (#11022)

* CI/codespell: revert changed-files action removal

This reverts commit eca9c1e539 from #10704.

Post this change codespell doesn't show annotations for the PR contents
as it now scanning the whole pages directory and completes execution
after showing a limited number of strings. This effectively made
Codespell unusable. Therefore I have reverted the change to fix
Codespell, the only issue being this would reintroduce the false
detection with annotations being
made in translation PRs on non-English pages.

* CI/codespell: use point release instead of master

Using the development branch isn't ideal for production as it is prone to breakage with a faulty bug or PR. So in this commit, I am updating the codespell action to use the point release instead for more stability and versatility.
