Standardize URL naming

[GDay]

Currently, we have a combination of hyphens and underscores in the names of the urls. For example here:

ChiefOnboarding/back/user_auth/urls.py

Lines 23 to 37 in 0f53e9a

	path(
	"password/reset_request/",
	PasswordResetView.as_view(
	template_name="password_reset.html",
	email_template_name="email/reset.html",
	subject_template_name="email/reset_subject.txt",
	),
	name="password-reset",
	),
	path(
	"password/reset_request/done/",
	PasswordResetDoneView.as_view(
	template_name="password_reset_done.html",
	),
	name="password_reset_done",

It would be good to make this more standardized to one of the two. I think Django goes with hyphens: https://docs.djangoproject.com/en/4.2/topics/http/urls/#examples by default.
