fix(nvidia): install legacy NVIDIA driver on older GPUs

[ashddev]

Fixes #3954

This PR updates the NVIDIA hardware install script to install the legacy NVIDIA driver for older GPUs (Pascal (10xx), Maxwell (9xx), Kepler (7xx)), as suggested in the recent Arch Linux announcement.

I don't know if it was always like this, but apparently Nvidia-utils is a dependency for Nvidia packages, meaning we don't need to install it separately.

[ashddev]

Fair it is a dependency, but I don't see a problem with being explicit here for the sake of clarity and in case dependencies change.

[Kn0ax]

Should we inform users whether their graphics card is currently supported by NVIDIA or by the Arch team?

Right now, the script assumes that if a user does not have a GPU newer than the Pascal architecture, it will get the 580xx driver, which is not supported by older cards, and users are likely going to be unaware of this.

[Kn0ax]

this should handle migration for mentioned cards
(sorry, i couldn't add this as a commit to current branch for some reason.)

Thanks for taking the time to review my PR!

Yeah it may be simplest to just inform the user if their GPU is legacy and unsupported based on this status table and direct them to the wiki if so.
