Meta Issue /assign Refuse Message

[0x4007]

The bot should explicitly refuse to assign meta issues. This can be confusing for new users so we should fully explain that have not been assigned to any task, and that they should navigate into the sub issues and assign themselves to those instead.

Skipping /assign since no time labels are set to calculate the timeline
