Fix description key inside type

This PR fixes a when a key named description is inside the type block of a variable section:

variable "ingress_cidr_blocks" {
  description = "Bzzzzz"
  type = list(
    object({
      description = string
      cidr_blocks = string
      from_port   = number
      to_port     = number
      protocol    = string
    })
  )

  default = [
    {
      description = "SG"
      cidr_blocks = "10.0.0.0/32"
      from_port   = 22
      to_port     = 22
      protocol    = "tcp"
    },
  ]
}
