cmd/cue: remove all "not yet stable" `cue mod` notes
All of these commands have existed since early 2024.
They have widespread use for authoring and consuming CUE modules today,
so treating them as not stable is not really sensible anymore.
Some of these, like `mod resolve` and `mod edit`, are not nearly as
common as `mod tidy` or `mod publish`. However, they were all added
around the same time and we have no plans to change the design of any.
