UX: suspend forever time period messages (#13776)
When the Forever option is selected for suspending a user, the user is suspended for 1000 years. Without customizing the site’s text, this time period is displayed to the user in the suspension email that is sent to the user, and if the user attempts to log back into the site. Telling someone that they have been suspended for 1000 years seems likely to come across as a bad attempt at humour.

This PR special case messages when a user suspended or silenced forever.
