add `about` command/endpoint to show the versions of the component installed in the board

[dido18]

Proposal: add a command to show the versions of the components installed on the board.

To better debug the issue of the end user, we could add a command to print the version of each component:

• name of the board
• deb packages
  • arduino-router
  • arduino-app-cli
  • arduino-cli
  • arduino-app-lab (apt show arduino-app-lab)
• core: version of the arduino:zephyr core (e.g arduino-cli core list)
• kernel version
• buildInfo: version of the Debian image
• serialNumber: the serial number of the board ??

Something like:

arduino-app-cli system about

Also, the HTTP endpoint could be added.

Possible command to get the deb packages versions

dpkg-query -W -f='${Package}: ${Version}\n' arduino-router arduino-app-cli arduino-cli arduino-app-lab
