Add doc tests, make them pass

* push.yml
   * Added documentation step which installs [docs], checks links and builds documentation to find any errors.
   * Need to install to get all the dependencies, because p4a code is imported during doc generation.
   * Updated rest of checkout action versions to be consistent with new code.

* apis.rst
   * http -> https
   * Disambiguated two modules with the same name.

* buildoptions.rst
   * Corrected indenting

* conf,py
   * Added language
   * Added two URLS to ignore that link-checker was failing even though they worked.

* ext/sphinix_rtd_theme/*
   * Old theme did not work with Sphinx 7.0+.
   * Removed it from source control. Install the latest each time.

* launcher.rst
   * This described an old feature that hasn't worked for years. Couldn't fix the links because the whole feature is gone now. Removed it. If the attempts to bring the feature back ever come to fruition, this can be restored and edited.

* index.rst
   * Removed no-longer-existing anchor,
   * Removed launcher page

* quickstart.rst
   * Removed launcher

* recipe.rst
   * Fixed syntax error in rst.

* services,rst
   * Fixed broken URL (and linked to project rather than bug-tracker.)

* troubleshooting.rst
   * http->https
   * Link to English rather than Chinese web-sites.

* setup.py
   * Add docs as extra.
