fix: Use PyInfo from rules-python

[honnix]

Depending on bazel and configuration, PyInfo is either the starlark implementation or built-in, which makes the code more compatible.

load("@aspect_rules_py//py:defs.bzl", "py_binary")

py_binary(
    name = "hello-world",
    ...
)

mypy_test(
    name = "hello-world-mypy",
    deps = [
        ":hello-world",
    ],
)

The above code fails because aspect_rule_py use PyInfo from rules_python.
