py(deps[dev]) ty 0.0.70 -> 0.0.73

why: Three pre-1.0 releases of a type checker, so its diagnostics can
move under this project. 0.0.71 diagnoses invalid `__getattribute__`
calls, validates boolean conversion in comprehension filters and the
shapes of unpacked callable arguments. 0.0.72 stops treating augmented
assignments as attribute definitions, improves assignability hints for
protocols and `TypedDict`, and diagnoses invalid module-level
`__getattr__`. 0.0.73 preserves variadic generics through
`functools.partial` and disambiguates same-named types in diagnostics.

what:
- uv.lock: ty 0.0.70 -> 0.0.73
