fix: Drop wheel from direct build dependencies (#175)

It was never necessary. In the past, `setuptools` would pull it in through the PEP 517 hook, only when building the wheels. During PyCon 2024, though, `wheel` moved into the `setuptools`' codebase and so it's always bundled now, in the modern versions.
