Allow pinning of clj-kondo version

[martinklepsch]

It would be great to be able to specify a clj-kondo version when running this action. The benefits would be that changes in clj-kondo can't break anyone's build and also people might upgrade more consciously, learning about new features in clj-kondo etc.

If you have ideas for how this might be implemented I might take a stab at it :)

Took a stab at implementing this in https://github.com/filipesilva/clojure-lint-action/commit/689f02b128699a830110ad948a9013c318225bd3, but it turned out to be a bit harder than I expected.

• to use a custom version in FROM, we need to use to use ARG: https://stackoverflow.com/a/63313197/2116927
• but there's no way to set it in Docker github actions
  • https://github.com/orgs/community/discussions/25241
  • https://docs.github.com/en/actions/creating-actions/metadata-syntax-for-github-actions#runs-for-docker-container-actions
• the workaround seems to be to use the GH action to create the docker image to then build and run it, but that feels too roundabout

Also see DeLaGuardo/setup-clojure#77 (comment), you can use setup-clojure with a version, and the settings described there to integrate directly with annotations.
