[nautilus-python] Created tag 4.0.alpha

[Jan Tojnar <jtojnar src gnome org>]

The unsigned tag '4.0.alpha' was created.

Tagger: Jan Tojnar <jtojnar gmail com>
Date: 1660336683 +0200

    - The extension was ported to Nautilus 43 
(https://gitlab.gnome.org/GNOME/nautilus-python/-/merge_requests/11)
      - Notably, this removes any direct access to GTK widgets from the API. **Most scripts will need to be 
modified.** Please check the migration guide in the docs on how to update your scripts.
    - Switched to Meson build system (https://gitlab.gnome.org/GNOME/nautilus-python/-/merge_requests/10)
    - Removed support for Python 2
    - Fixed build with `-fno-common` (Andreas Henriksson)
    - Added missing parent constructor calls to examples
    - Decorated the examples with typehints
    - Fixed several memory leaks (Michael Webster)
