Improve Lenovo X280 support

Hello!

Recently I got myself a X280 and found out that the libinput defaults for my laptops are a bit off. I decided to experiment with libinput's quirks and found some values that feel more natural.

For anyone interested in improving the experience even more, here are some tips for Fedora 37 (Gnome):

Measure your touchpad and apply the correct size

Use gnome tweaks to setup trackpad as area - style

Disable middle mouse emulation using:

gsettings set org.gnome.desktop.peripherals.mouse middle-click-emulation true
