Bundle latest ALTCHA version

[stefan6419846]

The package currently bundles ALTCHA version 1.4.2 (https://github.com/aboutcode-org/django-altcha/blob/main/django_altcha/static/altcha/altcha.min.js.ABOUT). In the meantime, version 2.0 (current version: 2.2.4) has been released, including WCAG accessibility compliance enhancements.

While providing a custom URL would be possible, it would be great for this project to at least indicate official version 2.0 support.
