Hardcoded ipv6 in nginx.conf breaks deployment

[k2patel]

Issue caused by #385 , Causing deployment to break.

• When ipv6 is disable at kernel level and docker level, it does not have any address ::0 where nginx can bind and fails to start.

I believe the better option to use the entrypoint.sh to modify the file based on sysctl value..

i guess something like..

# Check if IPv6 is enabled on the host
if sysctl -a | grep -q 'net.ipv6.conf.all.disable_ipv6 = 0'; then
    # Enable IPv6 configuration in nginx.conf
    sed -i 's/#listen \[::0\]:80;/listen [::0]:80;/' /etc/nginx/nginx.conf
else
    # Disable IPv6 configuration in nginx.conf
    sed -i 's/listen \[::0\]:80;/#listen [::0]:80;/' /etc/nginx/nginx.conf
