Describe the bug

The Developing on Metadata Ingestion docs at https://datahubproject.io/docs/metadata-ingestion/developing are missing Cargo as a requirement.

To Reproduce
Steps to reproduce the behavior:

1. Uninstall Cargo (if installed)
2. Run gradlew :metadata-ingestion:installDev (from https://datahubproject.io/docs/metadata-ingestion/developing#set-up-your-python-environment)
3. See error

  × Preparing metadata (pyproject.toml) did not run successfully.
  │ exit code: 1
  ╰─> [6 lines of output]

      Cargo, the Rust package manager, is not installed or is not on PATH.
      This package requires Rust and Cargo to compile extensions. Install it through
      the system's package manager or via https://rustup.rs/

      Checking for Rust toolchain....
      [end of output]

  note: This error originates from a subprocess, and is likely not a problem with pip.

× Encountered error while generating package metadata.
╰─> See above for output.

note: This is an issue with the package mentioned above, not pip.

I believe the root cause of this was delta-io/delta-rs#972, which has now been fixed (although it hasn't been released yet)

I'm closing this for now, but @remisalmon let me know if this issue is still present in a week and we can re-open it.
