v0.2.0

• Update provider version and OS regexes to capture all possible variants that are returned from the terraform registry today
• Added X-Terraform-Version request header for module calls
• Registry response to module version download path must be 204, not 200, because the server returns empty body. Download link is passed by means of X-Terraform-Get response header. Both terraform and opentofu support that (in fact they do support both 200 and 204).
• Added response errors to the model.
• Updated the regex for module download URL
• Added release github action, publishing the resulting openapi specification.
