How to use latest release with HTTP_ARCHIVE in WORKSPACE

[desh-woes]

Description

The samples included uses the Module files to override the rules for building the proto library.

However, the setup does not work for a plain WORKSPACE + Http archive combination, as it seems to require specifying a build file.

For context, I have tried

http_archive(
    name = "rules_proto_grpc",
    sha256 = "c6b30f95470792f9894e3b6b6ac271813a7b59f6cb43a09bca15213d309d45f9",
    strip_prefix = "rules_proto_grpc-5.0.0",
    urls = ["https://github.com/rules-proto-grpc/rules_proto_grpc/archive/refs/tags/5.0.0.tar.gz"],
)

And that does not work. Does anyone have a pointer for getting this to work using a WORKSPACE? Thank you.
