Note that this patch series needs the patch
`tui: don't abort install if min ram requirement is not met`
(https://lists.proxmox.com/pipermail/pve-devel/2023-July/058057.html) to
apply.

This patch series does two things:
1) It raises the minimum usable RAM the installer checks for from 1 GiB to 2 GiB.

Up until now the installer checked whether the system (pve, pmg and pbs) had at
least 1 GiB of usable RAM or else it would display a warning. However,
the pmg and pbs docs specify a minimum of 2 GiB of usable RAM. Off-list,
Thomas recommended having a min of 2 GiB for all products:

"We could just update the docs to use 2 GiB as minimum as:
- for PVE one normally wants more RAM anyway, for running guests and
   all that
- for PBS it just makes sense to have a good amount available for page
   cache
   or ZFS ARC
- for PMG the clamav service alone eats almost a GiB, so 2 GiB aren't
   that
   unrealistic there either."

2) It updates the docs to specify the minimum disk size for a pve install.

As of now, the pve docs do not specify the minimum disk space needed for
a pve install. Extrapolating from the Debian min requirements 
(https://www.debian.org/releases/bookworm/amd64/ch03s04.en.html) the
docs recommend a minimum disk size of 16 GiB. Leaving all the default values
in the installer (i.e. not changing any lvm-thin/swap sizes), this gives
a root directory of 6.8 GiB.
