In anticipation of #3127 happening, we need to ensure that we remove mentions of "experimental" on cuelang.org where appropriate. This issue captures that work.

The page mentioned in the initial comment is fixed in https://cuelang.org/cl/1194896 which came out of cue-lang/docs-and-content#147.

@myitcv does this issue track updates to the help texts (i.e. as per #3151), or can it be closed as a duplicate of cue-lang/docs-and-content#147?

The latter, thanks for catching the dupes.

Per the above exchange, the remainder of work here is captured by cue-lang/docs-and-content#147 so closing this issue as complete.
