CI/codespell: remove changed-files action, use point release of action (#10707)

* CI/codespell: remove changed-files action

Superseeds #10704

This change would make the CI run only on English pages by directly passing the path to Codespell to prevent false detections like https://github.com/tldr-pages/tldr/pull/10702/files for other languages, There still would be annotations made for other English pages not in PR similar to now, but it won't prevent us from merging the PR as we have the only_warn parameter set to 1.

* 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.
