This was commented prior to the
port to OpenAPI 3.1 for technical reasons (#1127).
Now we can use it just fine.

* keys.yml: fix one_time_keys object contents
The alternatives previously listed under two additionalProperties levels
are actually one _more_ level deeper; we still can't define them in
a formal way before moving to OpenAPI 3 but at least let's be honest
and say there's always a dict where there's always a dict. Also,
since the same data structure is used in three places now, at least
give it a name, and document the actual definition (once) separately
(not using it now because it's OpenAPI 3).
