Update .gitreview for unmaintained/2023.1

Also had to change one job to use branched tempest as
was done in stable/2023.2 [0].

[0] https://review.opendev.org/c/openstack/neutron-dynamic-routing/+/936738

Had to disable the scenario jobs as they rely on an os-ken
fix that is not in 2023.1, see depends-on.

Depends-on: https://review.opendev.org/c/openstack/neutron-tempest-plugin/+/945061
