cmd/cue: update which experiments are on by default
We again forgot to update `cue help environment` when
the embed and toposort experiments were turned on by default in v0.12.0.
https://cuelang.org/issue/3848 tracks automating this help text.
While here, add a TODO to remember to finish the toposort experiment
for v0.14, just like the TODO we already have for the embed experiment.
