ci: Stop prohibiting template strings in files with translations

It has been nearly two years since the last regression reported in
https://savannah.gnu.org/bugs/?func=detailitem&item_id=50920 has been
fixed, and no further regressions were reported in the meantime.

It looks therefore safe enough to not restrict ourselves, and start
allowing templates for all non-translatable strings again.
