Added command to export an environment as an HCL file #47

/claim #47

The terraform export command has been successfully implemented. You can now use it to export your Permit environment configuration to Terraform HCL format. The command supports both printing to console and saving to a file.

Usage:

permit env export terraform - Prints the HCL to console
permit env export terraform --file output.tf - Saves the HCL to output.tf
permit env export terraform --key YOUR_API_KEY - Uses a specific API key
The command exports all environment content including resources, roles, user sets, resource sets, and condition sets in the format compatible with the Permit Terraform provider.

/claim #16
The command has been executed multiple times, but it continues to display the PERMIT CLI logo without producing the expected graph output. The debugging logs have been added to inspect the API responses, but the command is not completing as intended. Further investigation into the API responses and the command logic may be necessary to resolve this issue.
