Description of the bug

Despite the skin_mesh operator defining one of its outputs as umap<int32, int32>, there is not dict type recognized as either input nor output for operators in this Enum: https://github.com/pyansys/pydpf-core/blob/b7475932cb947315b2a3009daf3ce32684d192af/src/ansys/dpf/core/common.py#L61

We should properly document and handle dict type operator inputs and outputs, or remove them.
