fix(teal.headscale)!: Remove conflicting areas

The .delta, .golf and .quebec area names conflict with real TLDs. This is
a problem because that means if you add `clicks.domains` to your search
domains you may end up having a conflict, potentially causing you to
resolve something to the wrong address.

To address this, let's remove them from our valid area names list.
