chore(deps): update module golang.org/x/net to v0.55.0 [security]

Wrap user-facing lookup errors through a new formatDNSError helper that
clears net.DNSError.Server so the " on <addr>" suffix no longer leaks the
upstream resolver (e.g. "on 127.0.0.11:53") to end users.

Closes: https://framagit.org/happyDomain/happydeliver/-/work_items/2
