Avoid `jq` where possible

Some minor tweaks if you don't have/want jq installed:

Line 111:

• This could simply be NAMESERVER=$(resolvectl dns eth0 | cut -d" " -f4) if you know eth0 is your normal interface.

Line 119:

• This similarly can be changed to ENDPOINT=$(curl -s https://ipinfo.io/ip)

Very valid request, I support this take.

BTW, numbers of both these lines have been increment recently. Now it's:

wg-peers/wg-peer

Line 112 in d359838

NAMESERVER=$(ip -j addr show $INTERFACE | jq -r '.[0].addr_info[0].local')

wg-peers/wg-peer

Line 120 in d359838

ENDPOINT=$(curl -s ipinfo.io | jq -r '.ip')
