Add version constraint of Terraform JSON Output Format

[bigwheel]

Internals: JSON Output Format - Terraform by HashiCorp

Note: The output includes a format_version key, which currently has major version zero to indicate that the format is experimental and subject to change. A future version will assign a non-zero major version and make stronger promises about compatibility. We do not anticipate any significant breaking changes to the format before its first major version, however.

For fool proof, version check and constraint are needed.
