Value for unconfigurable attribute in resource `aws_eip` causes terraform fail

Describe the Bug

The Module plan fails when provisioning EC2 instance because of the "aws_eip" resource vpc argument.

module "ec2" {
  source = "cloudposse/ec2-instance/aws"
  version     = "1.1.0"
  ssh_key_pair                = "ec2"
  vpc_id                      = module.vpc.vpc_id
  subnet                      = module.vpc.subnet_ids[0]
}

Looks like this happens if you're on a version of the AWS provider < 5.0.0: https://stackoverflow.com/a/76688048/22424139
