ci: skip unit test workflows when only ui or markdown files change (#32422)

* ci: skip unit test workflows when only docs or ui files change

Mirror the CircleCI backend path filter (.circleci/scripts/classify_changes.sh)
in the GitHub Actions unit test workflows by adding paths-ignore for ui/**,
docs/**, *.md and *.mdx to every test-unit-*.yml pull_request trigger

* ci: drop docs/** from unit test paths-ignore since the folder no longer exists
