This is a mistake that exists in this codebase for who knows how
long.
Cite mis-uses the messaging system a lot for internal things we still
want to customize somehow, but are not labels that will ever be shown
on the screen. The prefix/suffix messages in this patch are meant to be
part of the HTML in id="…" attributes. Prefix/suffix must be a static
plain text strings. Using e.g. {{GENDER}} or {{PLURAL}} in these
messages is not even possible because there is no $1 parameter to use.
Note how all other similar messages already use ->plain().
A few wikis override these messages, but stick to the plain-text
convention, as they should:

This will continue to work.
This has minor performance implications. Fetching these messages is
faster if we can skip transformations.
