[Documentation] Should README setup example use http_archive rather than git_repository?

[wadejensen]

http_archive seems to be the standard method for pulling rules into a WORKSPACE in the bazel ecosystem. Should the README example for this repo

https://github.com/google/subpar/blame/9fae6b63cfeace2e0fb93c9c1ebdc28d3991b16f/README.md#L14-L24

be changed to something like the following?

# Subpar
subpar_version = "35bb9f0092f71ea56b742a520602da9b3638a24f"  # 2.0.0

http_archive(
    name = "subpar",
    sha256 = "34bb4dadd86bbdd3b5736952167e20a1a4c27ff739de11532c4ef77c7c6a68d9",
    strip_prefix = "subpar-{version}".format(version = subpar_version),
    url = "https://github.com/google/subpar/archive/{version}.tar.gz".format(version = subpar_version),
)

This saved me, you should send a PR to the README!
