Consider adopting Git versioning in our projects

See https://github.com/palantir/gradle-git-version and https://github.com/qoomon/gradle-git-versioning-plugin.

This can both help eliminate some version misalignment issues for developers and make it easier for Copilot.

A downside of this is that a developer may need to more frequently edit the commit version when iterating and debugging. Note that the GitHub Actions workflows might also need to be updated if the Git info is not available with ordinary actions/checkout.

An additional step might be to publish such artifacts to GitHub Packages instead of setting up the CI to pull these projects and publish them or asking copilot to do so (which is already configured in some projects). Doing this should be easier given we have enough space in GitHub Packages. Related to #3.
