python3Packages.ty: init at 0.0.20 

Similar to `python3Packages.ruff` and `python3Packages.uv`, the Python
module for ty allows for the ty binary to be searched for, e.g. for
subprocess CLI invocations.

This derivation uses the same tricks to speedup its build by referencing
the nixpkgs ty binary instead of rebuilding from scratch.
