Remove other subdomains from searches on DuckDuckGo
When searching on our website, DuckDuckGo gives results for all subdomains of tails.boum.org by default. These include:
-
staging.tails.boum.org
Worked around in 5cab8a92, until the real fix in #17934 (closed).
-
gitlab.tails.boum.org
We should avoid that once we have our own domain name (#18289) by hosting our website under www. by default.
