[release/3.1] update Ubuntu and Alpine RID

[wfurt]

This is port of dotnet/runtime#37031 to add new RID for Ubuntu and Alpine releases.

fixes dotnet/runtime#37000

I'm not sure what the approval process is for this @danmosemsft.
Discussion in #42871 sugests "tell-mode" but I'm not sure if that is still correct.

@wfurt my bad, missed your question. you do not need approval for RID changes and other changes just related to keeping up with distros. just set servicing-approved and @Anipik will merge it. (It's best for him to merge as sometimes branches are closed)

Should there be a change for 2.1 as well?

[wfurt]

I don't know @danmosemsft. I can look at 2.x history and craft PR as well if needed.

[danmoseley]

@wfurt I verified at tactics -- yes, please port to 2.1 and again consider approved, for anirudh to merge.

[danmoseley]

@Anipik is branch open? that's why i figured it's best that you do all the merges

[wfurt]

ops. sorry. I can roll it back.

[danmoseley]

I'll let @Anipik say but almost surely it's fine. I just don't keep track of when branch is open or not.

[Anipik]

The branch is supposed to open next tuesday. I can help here and make sure we dont produce a new build.

[wfurt]

thanks.
