doc: update GSG with v3.2 changes

* install all Debian packages from /tmp (not ~/acrn-work)
* remove use of USB stick to copy files between dev and target (use scp)
* fix kernel version numbers (5.15.44 to 5.15.77)
* update parameters for debian_build.sh
* remove display of GRUB menu (ACRN now takes over target and
  automatically boots into hypervisor then Service VM
