Running v5 locally with act

[kodebach]

Since there is #121, I assume running locally with https://github.com/nektos/act (and therefore also using this action in gitea) should be supported.

However, when trying

      - name: Setup Gradle
        uses: gradle/actions/setup-gradle@v5

I get the following error

 Unable to resolve v5: unsupported object type

Which according to nektos/act#1600 happens, because v5 doesn't point to a commit directly and instead points to another tag (v5.0.0). Using v5.0.0 directly works, but that of course also pins the version.
