Increase upgrade AIO volume size

Ubuntu Jammy -> Noble AIO upgrade jobs are currently failing due to
the Docker LV being >90% full. This change increases the overall volume
size available to the instance, as well as increasing the LV size for
the /var LV as that was also >90% utilised.

(cherry picked from commit 9823037)
