Update site list to sherlockproject.xyz/sites

[sdushantha]

With these changes, the site list will be written to the sherlock-project/sherlockproject.xyz repo where the docs and everything is located. This way, we wont have to manually update the list on the website.

Note to self: blacklist site-list.py from the regression testing as its not needed. The reason why it got executed is because we set '**/*.py' as the rule

When docs becomes a thing, would it be better moved over there? Or left here? Not sure myself

[ppfeister]

Oh it's already a thing
And no subdomain now

Disregard

@sdushantha Ironic, because running tox locally now flags site-list.py as failed for the ruff lint

This raises the question of why isn't that tox item running on ci though....only local....
