Semi-automatic update. These checks were done:
- built on NixOS
- Warning: no binary found that responded to help or version flags. (This warning appears even if the package isn't expected to have binaries.)
- found 2.33 with grep in /nix/store/axjjpwcbb3s56m0fk68y8w8vji56f2a5-libinput-gestures-2.33
- found 2.33 in filename of file in /nix/store/axjjpwcbb3s56m0fk68y8w8vji56f2a5-libinput-gestures-2.33
xf86-input-synaptics is unmaintained, and touchegg doesn't work with
the latest synaptics driver or libinput. Ideally DEs would implement this
themselves, but at least KDE/Plasma doesn't (yet)
