feat: lint workflow files and others files in .github (#16914)

* add npm prettier dep and format script to .github folder

* initial work on prettier formatting test

* attempt index notation

* change name of .github job to be valid

* another use of index notation

this is getting overcomplicated

* Change job ID to `github-files-formatting` and chane the name to `.github Files Checks`

* Change job name to `.github Files Formatting`

* Update Makefile with .github module and `filter-out`s

* run prettier formatting as added in this PR

.github/workflows/pr-label-validation.yml
