fix: set skip_infer_tables explicitly in `test_partition_via_api_wi…

…th_no_strategy` (#3057)

### Summary

A `partition_via_api` test that only runs on `main` was
[failing](https://github.com/Unstructured-IO/unstructured/actions/runs/9159429513/job/25181600959)
with the following output, likely due to the change in the default
behavior for `skip_infer_table_types`. This PR explicitly sets the
`skip_infer_table_types` param to avoid the failure..

### Testing

After temporarily removing the "skip if not on `main`" `pytest` mark,
the [unit tests
pass](https://github.com/Unstructured-IO/unstructured/actions/runs/9163268381/job/25192040902?pr=3057O)
on the feature branch.
