[docs] API documentation errors

[eerohele]

Description

Two errors in the API docs:

1. According to the API docs, view.find_by_class() returns a Region. It actually returns a point (int).
2. According to the same API doc page, window.show_quick_panel() takes a keyword argument called on_highlighted. Actually, the name of the keyword argument is on_highlight.

Environment

• Build: 4074

I believe these and a lot of other inconsistencies are listed in #2290

Ah, you're right. Apologies for the duplicate. I'll close this one.
