HTTPS redirect: www to non-www

Hi,

I recently moved my static website from GitHub Pages to SourceHut pages. The website was previously at `https://www.manueluberti.eu`.

After the move to SourceHut, I can only use `https://manueluberti.eu`. I noticed that `http://www.manueluberti.eu` redirects correctly to `https://manueluberti.eu`, while `https://www.manueluberti.eu` does not.

What can I do to fix this?

Thank you
