Lack of some translations in 5.1.0

[rafsaf]

Hi!

Currently in 5.1.0 in new django_registration/activation_form.html after #247 there are some translations missing, for example:

At first glance:

django-registration/src/django_registration/backends/activation/forms.py

Lines 26 to 29 in a397174

	EXPIRED_MESSAGE = _("This account has expired.")
	INVALID_KEY_MESSAGE = _("The activation key you provided is invalid.")
	activation_key = forms.CharField()

I think this activation_key needs "label" label=_("Activation key") and beside that some "makemessages", "compilemessages" commands are needed because both error messages don't appear in any .po files. I can craft some PR in spare time.

But there are quite many languages supported here so maybe instead of bump each of them by individual developers (which looks to be the case in the past when i look on code base) maybe some more general solution is possible (AI generated translation or something, there are quite good nowadays).

To be honest, I never really touch the translation files. I can add the translation marker for the field label, but anything missing from the files themselves will need to be fixed by someone who knows what they're doing.

If you or anyone else has time to update the translation files, I'm likely to do a new release of django-registration once Django 5.2 is released (currently scheduled for April 2, 2025) and would be happy to include them.

I crafted some PR for Polish, but still there are almost all languages affected by recent changes, hopefully there will be more volunteers to fix them, I am not going to try chances with some automated translations for other languages I don't know.

Thanks for your comment/ping @ubernostrum and for maintaining this package.
