ERROR: cargoHash or cargoSha256 is out of date

Cargo.lock is not the same in /build/cargo-vendor-dir

To fix the issue:
1. Set cargoHash/cargoSha256 to an empty string: `cargoHash = "";`
2. Build the derivation and wait for it to fail with a hash mismatch
3. Copy the "got: sha256-..." value back into the cargoHash field
   You should have: cargoHash = "sha256-XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX=";
