`resend_activation` action uses `password_reset` permission from settings

[73VW]

Hello there,

As mentionned in the title of this issue, resend_activation action uses the password_reset permission from the settings:

    def get_permissions(self):
        ...
        elif self.action == "resend_activation":
            self.permission_classes = settings.PERMISSIONS.password_reset
        ...

What is the reason of this? In my opinion, it should use its own permession or at least the activation permission.

I can open a PR in order to fix this if needed.
