this can easily add a few 100s KiB of text to the report on major upgrades,
this is just to verbose for an initial report.
I'd rather add just the count of available upgrades, i.e. lie `apt update`
does, which allows you to draw similar conclusions without bloating the
report to unwieldy sizes.

Maybe we could even add that info to the pveversion --verbose output,
as then it'd be already included here and also help on other channels
like the forum.
