Update zabbix_container.conf

[Linrador]

• Updated ct.memory.size and ct.swap.size to use coordinates instead of strings to match non english os.
• Updated ct.cpu.load to use /proc/loadavg so it'll retrieve the avg load times in the correct format (also non english os related issue)

Thanks, the original code did not worked for me (Debian 11,12), but this is working fine.
