Bzlmod setup does not use CARGO_BAZEL_URLS for crates universe

[csmulhern]

The bzlmod extension appears to rely on @cargo_bazel_bootstrap directly, rather than relying on CARGO_BAZEL_URLS to skip bootstrapping, as the repository rule does.

See:

https://github.com/bazelbuild/rules_rust/blob/fe610dab73c3c61560a547bc661177dd5115fed7/crate_universe/private/module_extensions/cargo_bazel_bootstrap.bzl#L28

https://github.com/bazelbuild/rules_rust/blob/fe610dab73c3c61560a547bc661177dd5115fed7/crate_universe/private/crates_repository.bzl#L244-L249

Is there any progress on this issue? This is preventing us from switching rules_rust to bzlmod (and in turn, due to complicated dependency issues, blocks our entire project from switching).

This should be fixed by #2570.

Yes, thank you.
