crates_vendor: [patch.crates-io] fails to patch primary/transitive dependencies for `path = "..."`

Using `[patch.crates-io]` in your `Cargo.toml` to patch to local copies of a crate via `CRATE_NAME = { path = "path/to/crate"}` is currently failing with an error of style: `Error: The package 'Name("zerocopy") Version { major: 0, minor: 6, patch: 1 }' has no source info so no annotation can be made`. This fails for patching both primary and transitive dependencies.

The error is coming from [this line](https://github.com/bazelbuild/rules_rust/blob/main/crate_universe/src/metadata/metadata_annotation.rs#L234), referencing the [package's `Package.source` being None, which is expected for a local project](https://docs.rs/cargo_metadata/latest/cargo_metadata/struct.Package.html#structfield.source).

This same workflow functions for its `CRATE_NAME = { git = "git_repository"}` equivalent.

Minimal repro:

## Command:
`bazel run //:crates_vendor`
