Document factory_kwargs in nn.Quantize + remove Attributes section (#59025)
Summary:
The `factory_kwargs` kwarg was previously undocumented in `nn.Quantize`. Further, the `Attributes` section of the docs was improperly filled in, resulting in bad formatting. This section doesn't apply since `nn.Quantize` doesn't have parameters, so it has been removed.
