Upgrade to Wagtail 5.2.x

[lparsons396]

This PR upgrades Wagtail to version 5.2

See Monday ticket & Wagtail 5.2 release notes.

This branch builds on the Wagtail 5.1 upgrade #544

The upgrade considerations actualise many of the deprecation warnings is the 5.1 upgrade and so few changes have been necessary here. Upgrading Wagtail has also necessitated the upgrading of django-filter (22.1 -> 23.4) and django-modelcluster (6.0 -> 6.1). All packages have been checked against the package board and use the appropriate tag / branch as needed.

Hi @lparsons396 Thank for doing this. There's a few dependencies that could do with been bumped to latest releases before is merged.

[zerolab]

let's match this with the production version (which is 13.12 at the moment).

Suggested change

	Django = "4.2"
	Django = "~4.2"

as = "4.2" literally asks for version 4.2, not 4.2.x

@helenb imho this is ready to go too

From @katdom13 on slack:

"I’m also encountering this error during staging deployment for 5.2:
TypeError: cache_control didn't receive an HttpRequest. If you are decorating a classmethod, be sure to use @method_decorator.
I can replicate this. I reverted the change on staging for now and will investigate this along with the above tomorrow."

I will also need to wait to hear if 5.2 has been tested on staging.

TypeError: cache_control didn't receive an HttpRequest. If you are decorating a classmethod, be sure to use @method_decorator.
@helenb @katdom13 the fix for that would be wagtail/wagtail.org@3410fbc

This fixes the error on app startup

cache_control didn't receive an HttpRequest. If you are decorating a classmethod, be sure to use @method_decorator.

Hi @helenb ,
Apologies, I reverted this yesterday on staging when I saw the errors, but failed to remove the tag here in this MR. Staging should still be in 5.1
