[JENKINS-71772] Remove runtime dependency on authorize-project plugin

https://issues.jenkins.io/browse/JENKINS-71772 notes that
a5f2767
inadvertently changed the authorize-project plugin from a test dependency
to a runtime dependency.  The code compiles correctly without the runtime
dependency and the tests pass on my Linux computer with Java 11.

jenkinsci/bom#2340 added authorize-project plugin
to the plugin bill of materials because I didn't detect that the new
dependency was not needed at runtime.

Thanks to James Holderness for reporting the issue.
