Type Hints

• type hints for translatable strings
  • flask_babel:LazyString
  • flask_babel:gettext returns a already translated string. there is no type to check other then string which doesn't help in the translatable context

examples

• in Check of in invenio-checks it would be nice to know if id is of type Final[str] Final and title are of type LazyString. that would people who are working on translations help to know if those strings have to be marked as to translatable strings
