Set default password for GNOME login

For consistency, set the same default password for console images.

I decided to set default password to default almalinux user for GNOME login.

Because gnome-initial-setup is only ignited if users (uid >=1000) does not exist but cloud-init automatically creates default user. I have created a wiki page for cloud-init documentation. https://github.com/AlmaLinux/raspberry-pi/wiki/How-to-use-cloud-init-to-configure-image

Let me merge this before updating images to 9.2.

The wiki article should probably be moved to wiki.almalinux.org for consistency under the Documentation -> Raspberry Pi subsection: https://wiki.almalinux.org/documentation/raspberry-pi.html

Indeed
