Allow to publish a Terraform provider to the official Terraform registry

[teneko]

Currently you can write Terraform providers in C#, but currently there exists no workflow to create artifacts that can can be recognized by Terraform registry.

What needs to be done:

• Check rules and constraints for artifacts that get produced by Goreleaser, uploaded as GitHub artifacts and finally recognized by Terraform registry
• Checkout .NET supported runtimes and identify what is not supported
