Fix or investigate intersphinx mappings.

Fix or investigate intersphinx mappings. Specifically the Schema class would be valuable as a link.Ben shared that the NVT workflow page is an example with an intersphinx link to merlin.io.Dataset.

This is in the nice-to-have category and not a blocking requirement for any release.

I spotted one mistake (mine) in the models repo, in the docs/source/conf.py file, the "main/core" should be "core/main".

intersphinx_mapping = {
    "python": ("https://docs.python.org/3", None),
    "cudf": ("https://docs.rapids.ai/api/cudf/stable/", None),
    "distributed": ("https://distributed.dask.org/en/latest/", None),
    "torch": ("https://pytorch.org/docs/stable/", None),
    "merlin-core": ("https://nvidia-merlin.github.io/main/core/", None),
}

However, making that correction with the latest code in main and rebuilding the doc does not make Schema in the in API documentation for DCNModel into a link to the Merlin Core documentation.

More troubleshooting and research is needed. I want to correct it, but my understanding is that this is a nice-to-have.
