After updating from Debian buster(10) to bullseye(11) I am getting KeyError: 'total_cache'.

installed Docker : 5:20.10.103-0debian-buster
installed check_docker: 2.2.2

Exception:
"check_docker", line 541, in check_memory adjusted_usage = inspection['memory_stats']['usage'] - inspection['memory_stats']['stats']['total_cache'] KeyError: 'total_cache' UNKNOWN: Exception raised during check': KeyError('total_cache')

inspection.json.gz

My current "fix" is to skip the adjusted_usage, and only use inspection['memory_stats']['usage']
