Subject: [PATCH] fix(warp): correct IPv6 address removal sed rule for
 IPv4-only VPS

The old sed rule only matched lines starting with IPv6 patterns, but
wgcf generates `Address = IPv4, IPv6` on a single line. This caused
the IPv6 address to remain in wgcf-profile.conf on IPv4-only VPS,
making wg-quick@warp fail with "RTNETLINK answers: Permission denied".

The new rule strips `, <ipv6>/<prefix>` from the Address line, leaving
only the IPv4 address.
