Change array-api-tests run command

This should resolve the following ModuleNotFoundError seen in the logs:

```
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/home/runner/work/dpctl/dpctl/dpctl/__init__.py", line 38, in <module>
    from ._device_selection import select_device_with_aspects
  File "/home/runner/work/dpctl/dpctl/dpctl/_device_selection.py", line 20, in <module>
    from ._sycl_device import SyclDevice, SyclDeviceCreationError
ModuleNotFoundError: No module named 'dpctl._sycl_device'
============================= test session starts ==============================
