tool: Update toolchain, edition, deps

- Update toolchain to nightly-2023-09-07
- Update edition to 2021
- Update deps

`OpenHidDeviceError` is deprecated, and is removed in newer versions.
Replace it with `HidApiErrorEmpty`, because there are no descriptions
for what anything means so I just picked one that didn't require fields.
