Subject: [PATCH] DOC options must be a dict when used with
 extends_documentation_fragment (#21745)

* Fix string formatting
* Provide better tracebacks
* When options is None and extends_documentation_fragment is in use, add an error that options must be a dict
* If options was specified and not a dict, then error
