enable index add test (#111016)
Dynamo is swallowing a user exception when suppress_errors is set to True. There's an issue filed for that: https://github.com/pytorch/pytorch/issues/108798. In the meantime we still like the functionality in this test which works without the default setting (dont suppress errors) to not regress.
