typing_extensions should be a core dependency

[observingClouds]

Hi 👋 ,

Thank you for this great package! If I am not mistaken, the typing_extensions package should be a core dependency as it is used in core.py and loaded during module import.

Probably,

universal_pathlib/pyproject.toml

Line 63 in 3fc72fb

"typing_extensions; python_version<'3.11'",

should just move to the main dependencies.

Example of failing import:

 from upath import UPath
../../../.local/lib/python3.10/site-packages/upath/__init__.py:10: in <module>
    from upath.core import UPath
../../../.local/lib/python3.10/site-packages/upath/core.py:25: in <module>
    from typing_extensions import Self
E   ModuleNotFoundError: No module named 'typing_extensions'

( universal_pathlib-0.2.5)
