Remove unused milestone deprecation partial

Usage of this partial was removed in
8a29bcbd but the partial itself was not
removed. Delete it, and move the strings that were being tracked in the
HTML translations todo list to the pending sync section. They can be
removed completely after the next Crowdin sync.
