Change: [strgen] Change warnings for translations into infos (#9406)

Unless invoked with -w, --warning ("print a warning for any untranslated strings") or -t, --todo ("replace any untranslated strings with '<TODO>'").

Eints normally fixes the warnings after a Pull Request, so it is not really useful information for the developer to see as a warning.
