feat(glossy): Remove hide/hidden modifier

This modifier was not orthogonal with other modifiers (for example, it
could not be used together with :noindex)
Added documentation and modified test to reflect that @term[] with an
empty supplement has exactly the same result *and* is more orthogonal.

This partially reverts commit 5957432d5d.

 But for some reason you want it to actually say "an annoying report." You can do
 that like this:
