Fix monitoring script for macos (#88159)
The monitoring script is currently failing with AccessDenied when trying to access uss memory on mac because [psutil.memory_full_info](https://psutil.readthedocs.io/en/latest/index.html?highlight=memory_full_info) requires higher user privileges
Example failures:

I could also make this script run with sudo, effectively granting this permission. But I'm not entirely sure that we need uss memory for mac, so gracefully handling the error looks nicer
