automatic_failover_enabled keeps updating

[AndreiBrajnicov]

Description

Hello, the automatic_failover_enabled setting keeps updating to true, even though it's already set to true.
This issue also affects the latest provider version too ( 1.6.2 )

module "elasticache" {
  source  = "terraform-aws-modules/elasticache/aws"
  version = "1.6.0"
  cluster_id                 = var.environment
  replication_group_id       = var.environment
  create_replication_group   = true
  create_security_group      = false
  subnet_ids                 = module.vpc.database_subnets
  security_group_ids         = [module.redis_sg.security_group_id]
  engine_version             = "6.0"
  node_type                  = "cache.t4g.micro"
  maintenance_window         = var.maintainance_window
  snapshot_window            = var.backup_window
  multi_az_enabled           = true
  automatic_failover_enabled = true
  az_mode            = "cross-az"
  num_cache_clusters = 2
}

Here is the output of terraform plan:

  # module.elasticache.aws_elasticache_replication_group.this[0] will be updated in-place
  ~ resource "aws_elasticache_replication_group" "this" {
      ~ automatic_failover_enabled  = false -> true
        id                          = "prod"
        tags                        = {
            "terraform-aws-modules" = "elasticache"
        }
        # (37 unchanged attributes hidden)

        # (1 unchanged block hidden)
    }

Plan: 0 to add, 1 to change, 0 to destroy.
