Pinned project validation fails when getting user preferences

[olevski]

String should match pattern '^[a-zA-Z0-9]([_.\-/]?[a-zA-Z0-9]+)*[a-zA-Z0-9]$' [type=string_pattern_mismatch, input_value='bethcg/renku-teaching-assignment-1', input_type=str]

From: https://sentry.dev.renku.ch/organizations/sentry/issues/9428/events/0862a32f453d47aca14b89161788112b/

The code where this happens is:

/app/env/lib/python3.12/site-packages/renku_data_services/users/blueprints.py in _get at line 245

        @authenticate(self.authenticator)
        async def _get(_: Request, user: base_models.APIUser) -> JSONResponse:
            user_preferences: models.UserPreferences
            user_preferences = await self.user_preferences_repo.get_user_preferences(requested_by=user)
            return validated_json(apispec.UserPreferences, user_preferences)
