feat(fedora/nvidia-*.sh): nvidia proprietary driver setup (continued from PR #319) (#370)

* feat(fedora/nvidia-*.sh): adding nvidia proprietary driver setup

* fix(fedora/nvidia-*.sh): removing update line

That update line crashed my system while testing, since it also
installed new kernal where I didn't build my driver. So new user can
also get confused.

* refactor(fedora/nvidia-*.sh): adding a new warning while starting the script

I faced this issue yesterday, So It's better to warn user before
installing this driver

* refactor(fedora/nvidia-*.sh): removing uninstalation option

For now, as suggested by @nnyyxxxx and @adamperkowski, I'm removing the
uninstall option until #362 gets resolved.

* Fix bashism
