docs: Ensures that the given database model (`DeclarativeMeta`) has a `query` property through
          which the user can easily query the corresponding database table.
  
          Database object models derived from Flask-SQLAlchemy's `database.Model` have this property
          set up by default, but when using SQLAlchemy, this may not be the case. In this method this
          problem we fix.
  
          Argumentss:
              model (DeclarativeMeta): The database model object whose `query` property should be
                                       set up if it's not set up already.
              session (Session): The session to use to set up the `query` property on `model`.
