Support actions/checkout@v6

[leonard84]

Please add support for v6. It was released 3 weeks ago.

@leonard84 sure, let me add the typings explicitly! #124

BTW, a partial support is in place by default - it's just the typings are used from v5. In practice it means that you should be able to use actions/checkout@v6 in your workflows, but through a class that is marked as deprecated. Is it the problem you're trying to solve?

By looking at the linked issue (spockframework/spock#2265), I think you're after solving another problem: your workflows fail on consistency check:

--- a/.github/workflows/branches-and-prs.yaml
+++ b/.github/workflows/branches-and-prs.yaml
@@ -20,7 +20,7 @@ jobs:
     steps:
     - id: 'step-0'
       name: 'Check out'
-      uses: 'actions/checkout@v6'
+      uses: 'actions/checkout@v4'
     - id: 'step-1'
       name: 'Execute script'
       run: 'rm ''.github/workflows/branches-and-prs.yaml'' && ''.github/workflows/branches-and-prs.main.kts'''

It happens because Renovate bumps the action's version in every occurrence, also in the consistency check job. github-workflows-kt as a library is still at v4 when it comes to the consistency check job (code). To update this version, since it's a breaking change across most users of the lib, we'd have to release the library under a new major version. I'm holding with that until some other breaking changes accumulate. I realize it's not optimal, sorry for the pain.

What I'd pragmatically advise you to do, and what I do myself, is manually revert the version bumps in the consistency check job to make use of the new checkout action in your actual workflows, and then close the PR from Renovate that still wants to bump the version in the consistency check jobs. It will make Renovate ignore only v6, and for the next versions, it will create a new PR with bumping versions across the YAMLs.

If you strictly need to use v6 in the consistency check jobs, let me know - we can discuss adding some backward-compatible feature of overriding the action's version in the consistency check job. I'd be totally fine with it.

Resolving this one - whatever comes from the above discussion, feel free to create a separate ticket, perhaps in https://github.com/typesafegithub/github-workflows-kt.

@leonard84 here's an idea for a feature I came up with: typesafegithub/github-workflows-kt#2157
