[BUGFIX] Remove deprecated package distutils and use pkg_resources instead.

[ItamarShalev]

To avoid warnings of deprecated packages. Please replace the line: from distutils.version import StrictVersion as Version

with: from pkg_resources import parse_version as Version

you can find this line in :

• customtkinter/windows/ctk_tk.py

• customtkinter/windows/ctk_toplevel.py

• customtkinter/windows/widgets/appearance_mode/appearance_mode_tracker.py

Example warning when I run pytest in my project:
