Towards #230

Nice! There's nothing I can complain about 👌🏻

What I think could make this even better, is by adding an overload for float -> float64, and one for (NDArray[np.float64] | _NestedSequence[float]) -> NDArray[float64].

One reason for this underlying thought is that float64 is (by far) the most commonly used floating type.
But the most important reason, is that if you have some function f(x: float), you're not allowed to pass a floating argument, but it is valid to pass it a float64. See for example numpy/numpy#28076 (comment) for some real-world examples of how this could cause problems for e.g. matplotlib.
