Disable flaky linalg.det.singular tests on ROCm (#96707)
Related issues: https://github.com/pytorch/pytorch/issues/93044 and https://github.com/pytorch/pytorch/issues/93045.
* No access to runner to debug ROCm flakiness
* Haven't seen any update on the two issues above
* Tests are still flaky whenever they are closed
### Testing
The tests are skipped https://ossci-raw-job-status.s3.amazonaws.com/log/11976899251
