TemplateDoesNotExist error from Generic Choose template

[RandomJo]

When I upgraded to wagtailstreamforms 4.0.4, I got a TemplateDoesNotExist error for the template at generic_chooser/templates/generic_chooser/widgets/chooser_v4.html.

I was able to fix this temporarily by adding "generic_chooser" to INSTALLED_APPS in settings.py. Then I could run ./manage.py collectstatic and the file was picked up appropriately and placed into the static files directory.

I would expect this file to automatically get picked up just by having "wagtailstreamforms" in INSTALLED_APPS. Or, if we have to add "generic_chooser," maybe that can be solved by updating the wagtailstreamforms documentation.

Run: pip install wagtail-generic-chooser
Then add generic_chooser to your project's INSTALLED_APPS.
Then it should work.
