Update AURA Web sample config default setting for Certbot
Since this often leads to confusion, change the default setting in the sample config from:
# Disable if you want to handle ssl yourself (e.g if you are deploying behind a reverse proxy)
# AURA_HOST_CERTBOT_ENABLE=false
to
# Certbot is enabled by default; Set to `false` if you want to handle SSL yourself (e.g if you are deploying behind a reverse proxy)
AURA_HOST_CERTBOT_ENABLE=true
