Steps to reproduce:

1. Use the template Proxmox VE by HTTP on a Installed proxmox
2. Create a vm template in the proxmox
3. The VM template is listed as a VM in QEMU discovery
4. Zabbix template create a down trigger:  "Proxmox: VM [xxx/template (qemu/xxx)]: Not running"

Result:

The template VM is seen as "down" from Zabbix while it is by design that it should be down.

Expected:
The template VM should be excluded from the discovery or from the item that fetch the ressources, that can be done via a preprocessing JSON:

```
$.data[?(@.template != 1)]
```

I added it on "Proxmox: Get cluster resources" but you could want to fetch the template as ressource to check if they exist ? So I'll let you decide where it seems the best fit.

Thanks for the work, have a nice day and coffee
