Minor docstring error in TensorInputType

[alealv]

The Docstring says:

    (2) string:
        Verify different input parameters binding with the same `type_domain` are the same data type.
        This additional check is done by defining a `type_domains` dictionary in the Operation class
        For example:

        ```
        class conv(Operation):
            input_spec = InputSpec(
                x=TensorInputType(type_domain="T"),
                weight=TensorInputType(type_domain="U"),
            )

            type_domains = {
                "T": (types.fp16, types.fp32),
            }
        ```
        would verify:
        (i) `x` and `weight` are one of the float16 or float32 type.
        (ii) `x` and `weight` are the same type.

(2) string:

But I think should be changed to:

Thanks @alealv for pointing it out! Yes, I believe it is a typo.

Could you please put up a PR with your proposed change? Thanks again!
