Add ZSA Voyager preset

I feel the ZSA Voyager is a popular enough keyboard to add as a preset, no? This is admittedly entirely self-serving, as I do not feel like creating my own preset for the Voyager. Thank you for your consideration.

Start by locating how existing keyboard presets are represented and checking any relevant tests. Add the ZSA Voyager preset in the same form as the existing presets, then run the relevant checks and confirm that the Voyager appears as an available preset.
