Update timeago to the latest release
Problem to solve
Update timeago.js to the v4.0.0, this version removes the jquery dependency, which is currently causing us to include a very old version of jquery in our nodemodules (jquery 2.0.48) in addition to our newer version of jquery that we use elsewhere.
The new version removes that old jquery dependency. Change notes here: https://github.com/hustcc/timeago.js/issues/200
Further details
Having the older version of jquery present results in security scanners flagging the assets as vulnerable, and causes unnecessary noise. This was brought up as part of: https://gitlab.com/gitlab-org/distribution/team-tasks/issues/502 (gitlab internal)
Testing
Risks: this is major version change, and comes with a slightly different API.
