cue: point out cue/format exists in the godoc
Given that stringifying a CUE value is a rather common need,
and none of the methods or types in this package help with that.
We also add a similar note to the String method,
as we anticipate that some users will look there first.
While here, stop listing the deprecated types;
that takes up valuable space and mental capacity for the reader,
and the types themselves already have visible deprecation notices.
