fix(scripts): checkout tag on release

[millotp]

🧭 What and Why

• The scala release is broken, because sbt-ci-release expects the GITHUB_REF to be a tag, not just a commit.
• Fix the kotlin release by using java 17, required by spotless.
• Fix the push-to-repository action.
• Update the gradle wrappers.
