Fix qubit metadata in identifying_hardware_changes

[dstrain115]

• This fixes the simple errors in the identifying_hardware_changes notebook from broken tutorial on identifying_hardware_changes.ipynb #5588.
• I am not sure this notebook is runnable though, as we no longer use sqrt ISWAP and the two-qubit metrics are missing.
