Bump django-hosts to 7.0.0

Supersedes:

• Bump django-hosts from 5.1 to 7.0.0 in /requirements #2105

I tested different versions and commits from the django-hosts repo and found that jazzband/django-hosts@591bf5d creates a behavioral change that results in some responses we test to switch from FOUND to OK. I'm not exactly sure why and I could some help to understand that.

I'm not exactly sure why and I could some help to understand that.

I don't understand why this PR was merged if nobody has been able to provide an explanation as to the behavior change. Did I miss a discussion somewhere?

Apologies, I overlooked that this PR was looking for further clarification. I reviewed, and status OK made sense to me (since I don't think those URLs are supposed to be redirected), and I saw the commit linked by @ulgens and it seems to add support for considering PARENT_HOST which was not supported before, which is what I assume caused the change in status code.

@bmispelon I am happy to revert the PR, if you think that makes more sense. Apologies on my part for missing that this PR was waiting on more discussion.

[ulgens]

I believe we won't need to revert the PR - it doesn't look like it's breaking or dangerous in any way, but I'd like to know more about what's causing the change on our end.
