register_pandas_dataframe crashes kernel when receiving dataframe with multiple columns with same name

My Synapse kernel crashed when I tried to register a dataset where the dataframe had multiple columns with the same name. I am not completely sure if this is the correct place to post this, but this is the best place I could find.

Minimum reproducible example:
```python
dataset = Dataset.Tabular.register_pandas_dataframe(
dataframe = pd.DataFrame([[1,2],[1,2]], columns=['a', 'a']),
target = datastore,
name = "bad_dataframe",
show_progress=True,
)
```
What I would expect:
To get some feedback about why it fails, and the kernel should not crash.

What I get:
```
Validating arguments.
Arguments validated.
Successfully obtained datastore reference and path.
Uploading file to managed-dataset/13e4b3c6-8730-4951-bde5-2d2bc6456e2d/
InternalError: Ipython kernel exits with code -11. Please restart your session.
```

Comece executando o exemplo de pandas DataFrame da issue com nomes de coluna duplicados e observe a saída do kernel. O payload identifica a fonte da documentação de TabularDatasetFactory em AzureML-Docset/stable/docs-ref-autogen/azureml-core/azureml.data.dataset_factory.tabulardatasetfactory.yml, mas nenhum arquivo de implementação ou teste é indicado. Considera-se concluído quando a falha retorna feedback útil sem causar o crash do IPython kernel.
