Move from libsass-python to Dart Sass #534
Description
libsass-python is EOL and no longer receives updates. The latest version of it has compat issues with setuptools 82+ because of the pkg_resources removal.
https://github.com/sass/libsass-python#libsass-python-sassscss-for-python:
LibSass has reached its end of life. It will no longer receive updates of any kind, nor will its wrapper libraries. Users should migrate to Dart Sass at their earliest convenience. See also https://github.com/attakei/sass-embedded-python.
In Alpine, mint-themes is the last consumer of libsass-python, so we can remove it from our repositories, after mint-themes switched away.
