[JENKINS-23561] Updated to split matrix-project-plugin

[JENKINS-23561](https://issues.jenkins-ci.org/browse/JENKINS-23561): `matrix.jelly` had to be moved to a different “package” when moved out of core, since there can only be one taglib for a given path. This was the one plugin other than `matrix-project` itself which was using that tag. So the easiest fix is to just publish a new release of it depending on the newly split plugin and with that taglib reference updated.
