[py] Fix typing in remote webdriver

[M1troll]

User description

Description

The main change is changing the return type hint for def get_downloadable_files(self) from dict to List[str], which is actually what is returned.

Also some cosmetic improvements have been added.

Motivation and Context

I caught some error from my static type checker () and saw that get_downloadable_files has the wrong type annotation and decided to fix it =)
