fix(resolve): Dont show locking workspace members

### What does this PR try to resolve?
This is for `cargo generate-lockfile` and when syncing the lockfile with
the manifest.
We still show it for `cargo update` because of `cargo update
--workspace`.

We hacked around this previously by filtering out the `num_pkgs==1` case
for single packages but this didn't help with workspaces.

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

### Additional information

This builds on #14440
