Make "Retire Game" Reversible

Rough draft posted above. Edits welcome. I am especially not sure about the blank lines.

I don't know if games will keep posting to Discord, so I did not mention in that in the examples of 'normal notifications'.

It almost seem to be that we should send the GM an email with this message (user controlled choice) with the "come back here" and "the game's threads" turned into URL links that they can follow later. What do we think?

It's pretty long, but I don't see anything that can be cut. It's probably fine
