fix(i18n): fix incorrect lookup of some translations The code had: _("some term %s here" % term) this extracts the template, but looks up the string with %s replaced. So the translation is broken. Changed to: _("some term %s here") % term which looks up the template and substitutes in the translation of the template. Found by ruff INT ruleset.
