Regression in 7.0.1 causes ImproperlyConfigured error for `account-email-verification-sent` endpoint (maybe others)

[vhsantos]

Description

After upgrading from version 7.0.0 to 7.0.1 of dj-rest-auth, the account-email-verification-sent endpoint raises the following error:

ImproperlyConfigured at /api/auth/registration/account-email-verification-sent
TemplateResponseMixin requires either a definition of 'template_name' or an implementation of 'get_template_names()'
Request Method:	GET
Request URL:	http://0.0.0.0:8000/api/auth/registration/account-email-verification-sent
Django Version:	5.0.10
Exception Type:	ImproperlyConfigured
Exception Value:
TemplateResponseMixin requires either a definition of 'template_name' or an implementation of 'get_template_names()'
Exception Location:	my_app/.venv/lib/python3.12/site-packages/django/views/generic/base.py, line 212, in get_template_names
Raised during:	django.views.generic.base.TemplateView
Python Executable:	my_app/.venv/bin/python
Python Version:	3.12.3

I believe that this issue is exposed due to a change in the URL definition for the endpoint in version 7.0.1 (PR #667) by @alexandrebarbaruiva

In version 7.0.0, the URL pattern for this endpoint was defined as:

re_path('account-email-verification-sent/', TemplateView.as_view()),

In version 7.0.1, this was changed to:

re_path(r'account-email-verification-sent/?$', TemplateView.as_view()),

Workaround

This issue can be temporarily resolved by rolling back to version 7.0.0.
