bullseye alpha3: graphical installer activated for arm64

[Holger Wansing <hwansing@mailbox.org>]

Hi,

I read in alpha3 release-notes about the activation of the graphical
installer for arm64.

This needs to be documented in the installation-guide then.

I have prepared a first patch for this, attached.

There are two points remaining open:
	- needed RAM: what is the minimal required RAM size for the use of
          the graphical installer (minimum_memory_gtk in the patch) ?
	- status of the graphical installer: is this considered stable, or
	  do we want to call this "experimentell" for now?


Thanks
Holger
