Pause assignments for @xFrednet (#14005)

I'll take a short break from auto assignments. My last few weeks have
been busy and I feel like getting my inbox back in order and taking a
short breather will be the best for me.

I still plan to review the PRs I'm currently assigned to and writing the
changelogs.

Jup that's it, have a good day, who ever is reading this =^.^=
