InstallingDrivers.md: Linux Mint bug prevents i386 package downloads from PPA

[dpanter]

Adding a PPA like Kisak-mesa is currently broken on Linux Mint 21, based on Ubuntu 22.04 LTS (Jammy).
The source list file is added with the condition arch=amd64 resulting in only amd64 packages being exposed. This in turn results in a broken Mesa installation on the system since you'll get stuck with version mismatches and can't install Kisaks 32-bit Vulkan drivers, among other things.

Removing arch=amd64 from the source list file allows installing all packages from the PPA and enables a properly working system.
File location: /etc/apt/sources.list.d/kisak-kisak-mesa-jammy.list

A bug reports exists. linuxmint/mintsources#242

You shouldn't use the Ubuntu PPAs on Linux Mint. Those are for Ubuntu.
