Update repository in pom.xml of plugin archetypes

The plugin artifacts are no longer published to the Google Cloud
Storage but to Maven Central.

To reference released artifacts from Maven Central it is not necessary
to specify a repository in the pom.xml. This is because by default
Maven tries to find any artifact in Maven Central.

The Gerrit snapshots artifacts are now published to the Sonatype
snapshot repository [1], hence this repository must be specified in
the pom.xml if snapshot artifacts are referenced.
