fix(ci/reviewdog): Flag files with CRLF line endings

[OnkarRuikar]

• addresses pr-check-lint_content workflow will not failed when there are only EOL changes translated-content#25244

Summary

When there is a file with CRLF(Windows) line endings pushed in a PR, Prettier converts them to LF. The workflow fails to suggest this change as a review comment, and the workflow doesn't fail either.

Solution

The git diff command doesn't consider CRLF -> LF as a change. CRLF -> LF change is not there in the diff output. Without the diff reviewdog can not make a PR comment.
As a workaround, we can flag files with CRLF and ask contributors to convert CRLF to LF.

Testing

Testing has been done in OnkarRuikar#44 (comment) and corresponding workflow run is: https://github.com/OnkarRuikar/content/actions/runs/12534736823/job/34955862300?pr=44#step:12:63

🪵 In the following files make sure all the lines end with 'lf' character and not 'crlf' characters:
i/lf    w/crlf  attr/text=auto eol=lf 	files/en-us/web/test/index.md
