Premature declaration of D12 compatibility

Note: I see the D12 compatibility was added so that the upgrade_status job would "work" when run against 11.1.x core. This is the wrong approach. It's pointless to run the upgrade_status job on every MR pipeline until you're actually getting ready to port to D12.

Good point, I think removing the upgrade status and core version requirement for D12 is fine until D12 is released and ready.
The changes look good to me. Will wait for one of the maintainers to have a look too before it is moved to RTBC+

Ok for me.

Thanks
Moving to RTBC+

Thanks everyone. Adding to release. 🍻
