CI: Dial back the non-voting jobs

As we are approaching 2025.1 release, we need to dial back our jobs
as we will surely create new jobs as a result of the branching.

We can do that then, but we don't need all of the non-voting jobs
right now, espescially those for 2023.2.

*also* moving the multinode job to non-voting so we *can* have
a chance of merging changes.
