Rollup merge of #110744 - weihanglo:cargo-credential-install, r=ehuss

bootstrap: update paths cargo-credential crate

This should be done in #110653 but forgot.

Fixes #110742

## How to verify this patch

Run `./x.py build cargo`. Previously it would fail with

```console
error: manifest path `/projects/rust/src/tools/cargo/crates/credential/cargo-credential-1password/Cargo.toml` does not exist
```
