Fix T66065: Missing text in the UI translations files due to 'fstring' usages.

Am not even sure that it is possible to use fstrings at all when UI
translation is required (that is, is a sensible, reasonable way that
does not make things even more complicated than they already are), but
one thing is certain, this won't be trivial to get it working, so
definitively not a job for now.

Instead just do not use fstrings for UI translatable strings.
