fix: handle maven release plugin generated tags
Look like 'my-awesome-project-0.1.0'; need to use a Pattern to slice out the semver triplet.
This pull request fixes a bug found while converting a project that previously used the maven-release-plugin; the tags generated by that plugin start with the project name, and can't be parsed by the Java SemVer library as is.
