This PR fixes #11157
This problem was likely introduced in #10532
When outputting to PyArrow, we create batches and then create a table from those batches.
When creating the batches we were deduplicating column names, but didn't do this for the schema passed to the table-from-batches function.
We properly skip deduplicating in both places now, Arrow has no problem with duplicate column names.
