* origin/fix-mocks-12-9:
  Remove `release` tag
  Fix make mocks command

The `release` tag is no longer used since the Runner assoicated with
that tag was removed in gitlab-com/gl-infra/infrastructure#9599

In `12-9-stable` we still use the old method of installing mocks which
was changed in 13.0 in
!2085. This
causes a failure in the stable pipeline in
