Fix release tag version on GithubAction CI

When building docker image with jgitver in the CI, jgtiver use a version pattern from file .mvn/jgitver.config.xml.

Maybe if we use <branchPolicies> correctly we can change the versionPattern when we are on branch master or maintenance.

Also, when building a release, we should not use maven cache, otherwise the artifacts used may have been build with an old project version.
