[py] Update type annotation to include WebElement

[cgoldberg]

User description

fixes: #15334

This adds WebElement to the type annotation for the frame_to_be_available_and_switch_to_it function in the expected_conditions module. The docstring was also updated to reflect this.

Motivation and Context

The type annotation was incorrect, since it was missing WebElement.
