Register GPG key with OpenTofu registry

[tparvu]

When initializing plugin with OpenTofu I get a signature error.

Initializing provider plugins...
- Reusing previous version of ansible/ansible from the dependency lock file
- Reusing previous version of hashicorp/aws from the dependency lock file
- Installing ansible/ansible v1.2.0...
- Installed ansible/ansible v1.2.0. Signature validation was skipped due to the registry not containing GPG keys for this provider
- Installing hashicorp/aws v5.43.0...
- Installed hashicorp/aws v5.43.0 (signed, key ID 0C0AF313E5FD9F80)

Could you register a key with the OpenTofu registry?
