fix(package): Register workspace member renames in overlay

This was reported at #10948 (comment)

I suspect there is a second bug here because my debugging only showed us
doing this for `val-json` and not `concepts` and only when building `utils`.

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.
