Description
Currently when a `[Float]` type resolves to `np.array([1, np.nan])` the generated payload is `[1, NaN]` which is not json-compilant (rather than `null`) without any warning. A custom scalar can do the job however as numpy is so widely used, maybe this should be supported out of the box?

Research direction
Start by tracing how Graphene's Float scalar or generated payload serializes NumPy arrays containing NaN. Reproduce the reported [1, NaN] output and add coverage showing that NaN is emitted as JSON null without breaking normal float handling.
