Description of the bug

From my reading of the documentation, I don't see any way to supress the docstring, and only show the summary line(s) of the docstring.
We are hoping to have 2 different blocks.... One will only show the summary (being a "non-technical") summary, and then another in a collapsed annotation that has the whole 9 yards.

This allows the documentation to be used for non-technical (non-programmers), using the summary only listing, And allow programmers to view the same documentation.

I see a "summary" option,

e.g. summary: true, appears to do nothing.

To Reproduce

 Example:

::: application.checkers.hoster.hostingclass
    options:
      show_source: false
      heading_level: 2
      parameter_headings: false
      merge_init_into_class: true
      docstring_options:
        ignore_init_summary: false
        trim_doctest_flags: false
      summary: true
      show_docstring_parameters: false
      show_docstring_raises: false
      show_docstring_receives: false
      show_docstring_yields: false
      show_docstring_warns: false
      show_docstring_description: false
      show_docstring_returns: false
      show_docstring_examples: false

As mentioned, using mkdocs w/mkdocstring[python] plugin, seems to work fine except I can't get the summary option to work.

Expected behavior

The ability to show the docstring summary, without the rest of the docstring.
