fix(package): Register workspace member renames in overlay (#15228)

### What does this PR try to resolve?

This was reported at
#10948 (comment)

For the exact mapping between the publish payload and the index,
see

https://doc.rust-lang.org/cargo/reference/registry-index.html#json-schema,
particularly the note about differences.

### How should we test and review this PR?

### Additional information

I suspect there is a second bug here because my debugging only showed us
hitting this scenario for `val-json` and not `concepts` and only when
building `utils`. That difference in behavior between a transitive and
direct dependency is odd.
