#68447: gitea portgroup: don't override dist_subdir; fix distname instead

     Type:  defect      |     Status:  assigned
 Priority:  Normal      |  Milestone:
Component:  ports       |    Version:  2.8.1
 Keywords:              |       Port:  gitea-tea
------------------------+-------------------------
 The gitea-tea port is dumping its [https://distfiles.macports.org/tea/
 distfiles] into the directory of the unrelated tea port. This appears to
 be the gitea portgroup's fault due to
 [220efec2a5ba90c2cd5e13db17cbc43b4ebdc903/macports-ports]. This was the
 wrong solution to the same issue discussed for the sourcehut portgroup in
 #68446.
