docs-bug(button): Missing documentation for MatButtonHarness with() static function

https://material.angular.io/components/button/api#MatButtonHarness

There is a static with() function that lets you find the right instance of mat-button on the page, yet this documentation doesn't support it.

https://material.angular.io/guide/using-component-harnesses states

You can also use the static with method implemented on all Angular Material component harnesses. This method creates a HarnessPredicate, an object that filters loaded harnesses based on the provided constraints. The particular constraint options vary depending on the harness class, but all harnesses support at least:

The docs for the with() function should exist on the Harness docs page as well, and not on this random guide.

Here is the function I am talking about:

Lumping this in but can file a new bug if needed.

https://material.angular.io/components/button/api#ButtonHarnessFilters states that there is a text filter on the filter interface. But, there is also the selector and ancestor filter from BaseHarnessFilters that isn't in that documentation.

I guess superclasses/inheritance isn't parsed when generating this doc?

@devversion do we extract API docs for static methods?
