Ubuntu 21.10 released

Ubuntu 21.10 brings a wide variety of improvements, most notably on the desktop side switching to GNOME Shell 40 and offering many improvements there including some theme refinements. There are also many underlying improvements to enjoy with Ubuntu 21.10, like what gets us excited about kernel and compiler upgrades along with other notable package version bumps.

Adding Wayland support for NVIDIA drivers is a big improvement, as is the addition of PipeWire. There's also a big regression in that Ubuntu has moved its Firefox package from deb to a Snap package, something I'd sure manually fix if I were an Ubuntu user.
