Description
Regression found by the 1.96 beta rustdoc crater run.
[INFO] [stderr] error: manifest path `/opt/rustwide/workdir/Cargo.toml` is a virtual manifest, but this command requires running against an actual package in this workspace
For comparison, here's the logs for the run using the 1.95 stable compiler: https://crater-reports.s3.amazonaws.com/beta-1.96-rustdoc-2/1.95.0/gh/catuhana.dirpc/log.txt

Research direction
Start by comparing the beta-1.96 and 1.95 crater logs linked in the issue, focusing on the rustdoc invocation and the virtual-manifest error. Reproduce the regression and trace the relevant rustdoc or workspace-package handling; done means the affected project succeeds under the 1.96 beta behavior as it did with 1.95.
