Remove a glossary term's translation in one language, with its review.
The glossary term stays, and so does the translation note.

The language must be one of the glossary's languages. Removing needs the
right to submit translations for the language in the glossary, and the
right to review it when the translation is reviewed. Both follow the
glossary's permissions, and need a plan that supports glossary editing.
A term with no translation in the language is a 404. Removing a
translation doesn't move the term's datetime_modified.
