Display a badge to indicate that a user is a GitLab Team Member

Problem

Community members cannot easily see when a GitLab employee is engaging with them on an issue, MR, Epic, etc

We also need to do this so that the GitLab team can see who's opened an issue for things like access requests.

Proposal

Using the logic implemented in !30884 (merged) display the following icon in these locations:

• After the Opened by firstname lastname before the emoji icon - !28257 (merged)
• After the firstname lastname in issue/MR/epic lists - e.g. https://gitlab.com/gitlab-org/gitlab/-/issues before the emoji icon - !28257 (merged)
• After the @username on issue/MR/epic/snippet comments (as per the below image) - !28243 (merged)
  • Prevent wrapping of badge on mobile #214089 (closed)

Design

Tooltip that says GitLab Team Member is displayed on hover.

Rule of thumb for placement of badge:

• If @username is displayed
  • The badge is displayed to the right of @username
• If @username is not displayed
  • The badge is displayed to the right of firstname lastname (before the emoji)
