This bumps the terraform provider to their latest version.
Hashicorp moved yet another provider to their organization
(`terraform-provider-helm`), so we need patch URLs in there as well.
The following proviers were not bumped:
- `google[-beta]`: It seems something changed again here with how
dependencies are provided.
- `nomad`: fails to build
- `lacework`: This one appeared fresh at `terraform-providers`, and
doesn't build (yet?)
