Show user popover for assignees/reviewers in MR sidebar
What does this MR do and why?
Note: This MR is a part of a series of MRs where we're making popover behaviour consistent across GitLab.
Shows user popover when hovered over assignees and reviewers in MR sidebar instead of plain tooltip. This also integrates the information on whether user can merge the MR or not.
Screenshots or screen recordings
Screenshots are required for UI changes, and strongly recommended for all other merge requests.
| Before | After | |

| User with merge rights |  |
