Include version catalog file in filehash in the Gradle cache key

Description: Add libs.versions.toml or *.versions.toml to the cache key for Gradle dependency caching.

Justification: Central declaration of dependencies is an incubating Gradle feature that supports centralisation of configuration of dependencies & versions. By convention this is done in a file named libs.versions.toml: https://docs.gradle.org/7.2/userguide/platforms.html#sub:conventional-dependencies-toml

Projects that start using this feature can’t practically use the Gradle caching feature in setup-java because the cache key will not change in most cases when dependencies are updated in the TOML file.

Are you willing to submit a PR? Yes - if this change is acceptable. Edit: no, as I will be using gradle/gradle-build-action@v2 instead which I discovered after raising this issue.

We’ll prepare a pull request later. We keep the issue opened until the pull request is merged. Thank you for the response and suggestion @3flex.

Sorry, I won’t be working on a PR.

On the best pattern, I’m not sure - **/libs.versions.toml would capture the conventional, default filename. If someone isn’t using the default filename then the file could be named anything as far as I know, so **/*.versions.toml is probably not that useful. I’d suggest **/libs.versions.toml to start with.
