Remove expires_in key

What does this MR do and why?

This MR aims to solve the issue #341248 (closed)

GroupMembersController#update and ProjectMembersController#update return an expires_in key. The value of the expires_in key uses distance_of_time_in_words_to_now which does not respect the User#time_display_relative setting added in #14560 (closed). So, we planned on changing it to use time_ago_with_tooltip. But the expires_in key doesn't seem to be used. So this MR removes the expires_in key.
