devstack-plugins-list: skip openstack/openstack

The proposal job to update the plugin list has been failing for a long
time as it gets a 500 error from gitea on the openstack/openstack
repo.  This is an odd "superrepo" with all projects as submodules;
thus openstack/openstack/devstack is actually a project, not the
directory with a plugin in it.

Skip this repo (gitea shouldn't return a 500, but that's another
thing...)

Regenerate the list manually for this run.
