Additional Python type hints

[AlbertoCentonze]

Description

I wasn't able to get the right suggestion for the code completion using pylance in vs code. That's why I started adding a few lines to improve the suggestions

Motivation and Context

I made these changes because I was working on a personal project and having those "type hints" really helped me

Types of changes

I only changed a few lines adding type hints. If this kind of changes are welcomed I'll continue to update the hints in the future when I use selenium and I need it

I had left those because the methods are deprecated but we can add it for now and then once Selenium 4 is released we will be deleting them

@AutomatedTester Where can I give a look at the new methods in Selenium 4?

I believe all the find_elements (plural) methods should return list[WebElement] and not WebElement
Am I mistaken?
Should I open a separate PR for this?
