Description of the bug:

If you specify this in your MODULE.bazel:

bazel_dep(
    name = "apple_support",
)

bazel errors with:

ERROR: Error computing the main repository mapping: module not found in registries: apple_support@_

I imagine omitting a version is supported for overrides(?), but i think ideally the error would hint to the user that they are missing the version.

What is the output of bazel info release?

release 6.0.0rc4
