Action resolution process?

[withinfocus]

Hello there -- we use an Action -- specifically https://github.com/actions/stale -- and with a recent release we noticed this linter (invoked via https://github.com/github/super-linter) isn't happy about it. Sample workflow config:

...

jobs:
  stale:
    name: Staleness
    runs-on: ubuntu-latest
    permissions:
      pull-requests: write

    steps:
      - uses: actions/stale@v4
        with:
          exempt-draft-pr: true

...

Note the @v4 release. Based on https://github.com/actions/stale/tags this is linked to the latest @v4.1.0 and the Action runs correctly, but this linter doesn't like exempt-draft-pr which seems acceptable based on the action.yml present in that repository. Furthermore, if we put almost anything in place instead of @v4 the linter will pass, and we assume that's some kind of resolution problem altogether.

Can there be some documentation expansions about the resolution process of a config? Even though this is a specific case, why is the linter not seeing this Action's latest properties?
