Version >=3.22 requires to add generic-chooser to the projects installed apps

[SusakiSir]

Expected behaviour

Installing wagtailstreamforms >=3.22 as the docs say without running into problems.

Actual behaviour

The template for the generic-chooser is not found and the tracelog doesn't even say it is requested by wagtailstreamforms, which made Troubleshooting very difficult...

The Error

TemplateDoesNotExist at /admin/pages/add/...
generic_chooser/widgets/chooser_v4.html

The Solution

To make sure the template can be found "generic-chooser" has to be added to the Projects installed_apps inside base.py as the documentation of wagtail-generic-chooser says: https://github.com/wagtail/wagtail-generic-chooser#installation

What i expect

Please add this required step of the installation to your documentation to prevent people going through hell fixing your errors.
