We've been running Gerrit 3.7 for some time now and seem very unlikely to revert at this point. Clean up the Gerrit 3.6 image builds as we don't need them anymore. THis change also comments out the 3.6 -> 3.8 upgrade job. Followup changes will add 3.8 image builds and test the 3.7 -> 3.8 upgrade process. Depends-On: https://review.opendev.org/c/openstack/project-config/+/881595 Change-Id: I759b34e48dcede7ffaa66c83da01b81c4fed4b4f
