Charlie Marsh e7beb7e1f4 [ty] Forbid use of super() in NamedTuple subclasses (#21700) ...

## Summary

The exact behavior around what's allowed vs. disallowed was partly
detected through trial and error in the runtime.

I was a little confused by [this
comment](https://github.com/python/cpython/pull/129352) that says
"`NamedTuple` subclasses cannot be inherited from" because in practice
that doesn't appear to error at runtime.

Closes [#1683](https://github.com/astral-sh/ty/issues/1683).
