Remove versions from the name of the packaging manager.
As also commented on BZ:
The script only expects to find a name here, not a version too.
See also maintainer role and how versions are handled there.
In this case I dont think it is really needed to still add that
distinction when we had two packaging managers in the past.
Test plan:
Look again at about.pl, Koha team, Koha development team.
Look at Mason James.
