Add type to parameter of webelement.WebElement.send_keys

[adamtheturtle]

Description

I have set the type of *value to AnyKey.
I chose AnyKey rather than str, despite the method docstring saying that value is "a string", because the method uses "".join(map(str, value)), which tells me that maybe a value element may not be a string.

Motivation and Context

Without this, pyright in strict mode gives me a reportUnknownMemberType error.

The Python folks in the project tell me that using str is more suitable, if you want to add this.

@diemol - sure, I made the change.
