fix: Change variable "node_security_group_additional_rules" from type map(any) to any

[pjrm]

Description

When trying to specify different types of security groups maps, the merge fail because the map is different. Example:

    # Override the default security groups, if web-proxy is enabled
    egress_8080 = {
      description = "First securit ygroup"
      protocol    = "tcp"
      from_port   = 8080
      to_port     = 8080
      type        = "egress"
      cidr_blocks = ["0.0.0.0/0"]
    }
    ingress_cluster_9443 = {
      description                   = "Another security group"
      protocol                      = "tcp"
      from_port                     = 9443
      to_port                       = 9443
      type                          = "ingress"
      source_cluster_security_group = true
    }
  }

This throws an error:
The given value is not suitable for child module variable "node_security_group_additional_rules" defined at .terraform/modules/eks.eks/variables.tf:200,1-48: all map elements must have the same type.

If the variable type is any, the issue no longer exists because the merge occurs without a problem.
