[py] extend typing options for get_property()

[eNcacz]

fixes #10624

Extend list of types which can be returned byt get_property() method.

Description

Current typing options does not cover all possible types returned by get_property()

For example

• clientHeight property is returned as int
• fooBar property is returned as NoneType
• childNodes property is returned as list

Motivation and Context

Linters (like mypy or PyCharm) complains about get_property() usage when we expect one of mentioned data type.
