.github/workflows: Don't run CI checks for markdown-only updates (#2347)

* .github/workflows: Don't run CI checks for markdown-only updates

Update the ci-prefixed workflows and ensure that CI isn't running when
only markdown files are updated.

* .github/workflows: Use paths-ignore instead of paths for ignoring certain files/paths

* .github/workflows: Remove the need to ignore the root doc/ path

The '**/*.md' filter pattern [1] should ignore _all_ markdown extension
files anywhere in the repository.
