Restrict TCP port 179 to worker-node sources.

The security groups allow all IPv4 and IPv6 sources through TCP port 179. If only worker nodes require BGP access, use worker-node CIDRs or the appropriate source security group for both address families.

around lines 306 - 309, Restrict the TCP port 179 ingress rule in the
security-group configuration to worker-node sources instead of allowing
unrestricted access. Replace the broad IPv4 and IPv6 sources with the
appropriate worker-node CIDRs or source security group, preserving equivalent
restrictions for both address families.
