Subject: [PATCH] Fixes for Python notebooks (#2472)

Follow-up to PR# 2455 and PR# 2467

* Fix for invalid notebook - hadamard_test.ipynb
* Remove explicit setting of target (default target is nvidia if GPU(s) present) - digitized_counterdiabatic_qaoa.ipynb

Addresses CI failures in the image validation step.
