New version of linuxserver/wireguard fails to create peer configuration when PEERS is set to string instead of int

[kostaleonard]

An update to linuxserver/wireguard breaks the VPN because the peer configuration file is not generated correctly. The PEER argument in the bootstrap needs to be changed from a string to an int. Here is a version that works on the EC2 instance:

ubuntu@ip-10-0-1-9:~$ sudo docker run -d   --rm   --name=bulwark   --cap-add=NET_ADMIN   --cap-add=SYS_MODULE   -e PUID=1000   -e PGID=1000   -e TZ=Europe/London   -e PEERS=1   -e SERVERURL=3.139.88.229   -e SERVERPORT=51820   -e INTERNAL_SUBNET=10.13.13.0   -e ALLOWEDIPS=10.0.0.0/8   -e PEERDNS=auto   -p 51820:51820/udp   -v /etc/wireguard:/config   -v /lib/modules:/lib/modules   --sysctl="net.ipv4.conf.all.src_valid_mark=1"   linuxserver/wireguard
