[pve-devel] [PATCH manager] pveversion: show upgradable package version in verbose output

[Alexander Zeidler]

when the state is "Installed", including not correctly installed, but
not for (residual) "ConfigFiles".

The information
* can be inaccurate for offline nodes or when using POM.
* is included in pveversion so it can also be used on public channels
  like the forum. The current System Report includes pveversion -v

 # pveversion -v
 proxmox-ve: 8.1.0 (running kernel: 6.5.13-5-pve)
 pve-manager: 8.1.6 (running version: 8.1.6/b7e8e914a1db70cc) [available: 8.1.10]
 ...
 vncterm: 1.8.0
 zfsutils-linux: 2.2.3-pve1 [available: 2.2.3-pve2]
