The literal string "string" is incorrectly quoted

[mcasperson]

When deserializing a property that assigns the literal value string to a property, it is incorrectly quoted.

A clear and concise description of what the bug is.

Software:

• OS: Linux
• Python version 3.11
• python-hcl2 version 7.3.1

Snippet of HCL2 code causing the unexpected behaviour:

variable "octopus_space_id" {
  type        = string
  nullable    = false
  sensitive   = false
  description = "The ID of the Octopus space to populate."
}

Expected behavior

The following script should produce output with an unquoted string value:

import hcl2

hcl = """variable "octopus_space_id" {
  type        = string
  nullable    = false
  sensitive   = false
  description = "The ID of the Octopus space to populate."
}
"""

parsed_config = hcl2.loads(hcl, with_meta=True)
example_ast = hcl2.reverse_transform(parsed_config)
converted_hcl = hcl2.writes(example_ast)

print(converted_hcl)

The result of this script is this:

variable "octopus_space_id" {
  type = "string"
  nullable = false
  sensitive = false
  description = "The ID of the Octopus space to populate."
}

Terraform does not accept this output as the type must be an unquoted value.
