Add support to Wagtail 5.0

[PrynsTag]

This update brings new features such as dark mode, SVG support, enhanced accessibility checker, and safer delete option. These features provide more options and control over content creation experience and make it easier to manage websites. It also has a lot of bug fixes and it drop the support for Django 4.0 that reached end of life on 1st April 2023.

Noticed this DeprecationWarning when running things just now:

RemovedInWagtail50Warning: Importing from wagtail.core.blocks is deprecated. 
Use wagtail.blocks instead. 
See https://docs.wagtail.org/en/stable/releases/3.0.html#changes-to-module-paths

I'm hoping to carve away some time to work on a PR for this, unless anyone's already got it started?
