init: fork of kejilion/sh with certbot host-network fix

- Replace 'docker run -p 80:80' with '--network host' for certbot standalone HTTP-01 to avoid timeout in environments where Docker NAT port-publish breaks LE inbound traffic but host port 80 is reachable.
- Applies to kejilion.sh (all locale variants) and auto_cert_renewal.sh.
- README install command points to this Gitea mirror.
