When the optional Unbound install is chosen with DoT forwarding, the script
truncated (>) /etc/unbound/unbound.conf.d/pi-hole.conf and rewrote it starting
with an indented "tls-cert-bundle:" option that has no "server:" section header.
unbound-checkconf rejects this ("syntax error, is there no section start"), so
"systemctl restart unbound" exits 1 and the install aborts (line 153). The
overwrite also dropped the interface/port 5335 settings Pi-hole forwards to.
Append (>>) the DoT additions to the existing recursive server block instead,
under a proper "server:" section (unbound merges multiple server: clauses), so
the tls-cert-bundle and forward-zone are valid and the resolver keeps listening
on 127.0.0.1:5335. Recursive (non-DoT) mode is unchanged.
