The GitLab wiki does not have much flexibility over the URLs. Let's move
it back to our shorter domain, wiki.wireshark.org. That way, we have
more control over the redirection process.

Other changes: Remove unused "TCP Chimney" that is not referenced
anywhere. It was originally added in the GTK UI via commit 66872335.
Prefer `Protocols/%1` to redirect short protocol abbreviations, this
reverts a previous fix for #17944.

Relates to #17999.
