Update mypy to 1.6.0

[cdce8p]

Proposed change

https://mypy-lang.blogspot.com/2023/10/mypy-16-released.html

• The type definition for dict.get was updated to better handle dict[str, Any].
  Previously the resulting type of get with a default value would be the type of the default value itself even though it can still be the value type of the dict (i.e. Any). The full workaround would be to use TypedDicts instead but this isn't always practical -> should not be done in this PR. Added type: ignore[no-any-return] instead. See 1214cbf

def f(a: dict[str, Any]) -> str:
    reveal_type(a.get("key", "default_val"))  # Previously 'str' -> Now 'Any'
    return a.get("key", "default_val")  # type: ignore[no-any-return]

• New import error codes -> import-not-found and import-untyped. Those allow for more precision than the ignore_missing_imports = true setting. For now, I've disabled both while removing ignore_missing_imports. In the long run, it might be possible to enable the import-not-found error code. Just not yet as it is also triggered for C-extensions without stub files. Mypy, in contrast to pylint, can't introspect those. See ab42401

• There is one small regression. I've reported it upstream and it's fixed already. Just didn't make the 1.6.0. Will be included in the next one. For now I've added a type ignore. See ae326f9
• Mypyc compiled wheels for Python 3.12 are now available on PyPI 🎉
