Release use versions from git tags instead of static value (#1002)

What changed?

gradle release now uses the version from git describe
added a handy task printVersion to get current version for release
simplify the git action
Why?

Release rc versions requires code commits which slows down the release process.
Now tagging a value would just release rc version easily

Future Plan

If everything looks good, we can change the action to closeAndRelease directly.

How did you test it?

Sample run

Repository is correctly closed.
