Clarify module publication status

The GitHub repo was temporarily renamed to tofu-aws-github-actions-oidc,
but had to be changed back to terraform-aws-github-actions-oidc in order
to claim the HCP Terraform public registry namespace. The README has
been updated to clarify that the module will continue to be published to
the HCP Terraform public registry. Apologies for any confusion this may
have caused.

 ## Required permissions
 
 Authentication is required for the AWS provider so that OpenTofu can apply configurations. The [IAM best practices](https://docs.aws.amazon.com/IAM/latest/UserGuide/best-practices.html) recommend granting least privilege.
