test: branch properties of main and release/*

[ARR4N]

Why this should be merged

Safer release process by enforcing invariants of release/* branches as automated in #137 to fulfil #25.

How this works

New test for go_tooling CI job.

If the PR target branch is main then only the params.ReleaseType is checked. If the target is neither main nor a release branch then the test is skipped. The checks performed on release/* branches are described in the test.

How this was tested

Locally against a dummy release branch with deliberate problems created by (a) including this PR's changes in the final commit and (b) not updating the libevm version.
