    Verify that a compatible npm_bazel_typescript is loaded a WORKSPACE.

    This should be called from the `WORKSPACE` file so that the build fails as

    check_rules_typescript_version(version_string = "0.22.0")

                      `VERSION >= version_string >= COMPAT_VERSION` where VERSION and COMPAT_VERSION
