…kflows/hashicorp.yml to v4.0.1 (#471)

This patch bumps hashicorp/ghaction-terraform-provider-release/.github/workflows/hashicorp.yml to v4.0.1, with the intention of using the new runner labels format (see release notes in https://github.com/hashicorp/ghaction-terraform-provider-release/releases/tag/v4.0.1).

This change is necessary for a runner to pick up jobs using this action.
