Add times/uuid?include_deleted=true parameter

[matthewrsj]

In conversation with @ElijahCaine and @LyonesGamer I learned that GET /times/:uuid?include_deleted=true is allowable.

All I can find in the docs currently is GET /times/:uuid?include_revisions=true

Please add a section describing the uuid - include_deleted combination.

Well, I found the information here: https://github.com/osuosl/timesync/blob/develop/source/draft_api.rst#reference-table

You might consider adding another section like this one: https://github.com/osuosl/timesync/blob/develop/source/draft_api.rst#get-timesuuidinclude_revisionstrue for :uuid/include_delted=true and put it in this section: https://github.com/osuosl/timesync/blob/develop/source/draft_api.rst#retrieving-deleted-objects-include_deleted
