Cleanup credentials.toml silently fails

[dsteeley]

The path to credentials.toml is incorrect resulting in the file not being removed.

Per https://doc.rust-lang.org/cargo/guide/cargo-home.html, credentials.toml should be in CARGO_HOME not CARGO_HOME/.cargo.

I've attempted to fix this however I've hit a issues the same as https://github.com/Swatinem/rust-cache/actions/runs/25352675231/job/74335488118.
I can propose a separate fix for this CI failure and then propose a PR for the credentials.toml issue.

I think you can ignore that CI failure, just looks like some outdated dependencies, and some typescript version related breakage.

I thought I would need to update dist with my change which I'm struggling to do due to the errors.
