[bugfix] Enable misspelling.py for several sites using wikidata

- collect misspelling categories from wikidata items Q8644265 or Q9195708.
  This enables the script for additional sites
- prefer templates over categories if misspelling_templates can be found
  by its sitename.
- use usual BaseBot option handling with MisspellingRobot. Therfore use
  kwargs for the options. Unfortunately DisambiguationRobot does not have
  a compatible interface. Therefore call SingleSiteBot.__init__ first and
  pass the options back to MisspellingRobot's super().__init__ but call
  their parameter by its name.
- enable kwargs with DisambiguationRobot and only set self.generator
  if the positional argument for generator is useful and not None
- rename createPageGenerator to generator which is used directly by
  run method.
