[release/7.0] add RID for Ubuntu 23.04

[wfurt]

It seems like the generation of RID tree no longer works. I had-pick changes from #82120.
It also seems like this is first platform update in 7.0 so I don't know if adding the servicing tags would be sufficient.
We should double check when build is out.

I couldn't figure out the best area label to add to this PR. If you have write-permissions please help me learn by adding exactly one area label.

OOB package changes look good.
@wfurt Do we not need macOS 13 and Android 32 new RIDs here like in the 6.0 PR?

cc @mmitche @rbhanda this is PR 2/2 that we need to wait for.

no. it is already there. I updated 6.0 for completeness as there is no special trickery AFAIK in those versions.
(unlike support for new architectures in Alpine)

CI is green. Merging now to unblock the internal->public merge PR.
