Improve wording of formatting partitions before applying changes

[42Willow]

Correct me if I'm wrong, as maybe I would've actually formatted my entire SSD :eyes:

I have an NVME SSD, I selected manual partitioning with archinstall and hit go. It then came up with a message saying formatting "/dev/nvme0n1 in 5, 4, 3," etc. As I didn't want to format my entire SSD (I am dual booting, and this is my main system) I cancelled. Could someone please tell me if it is safe to go ahead? If so, then there definitely should be a more verbose message - I only selected /dev/nvme0n1p5 and /dev/nvme0n1p6 to be formatted.

Two people in the discord support channel seemed to have had the same issue, but it wasn't resolved.
