fix: Use non-breaking switch for layer keys in picker.csv

This seems to be the easiest way to prevent these keys from taking three
lines.

I don't necessarily like dealing with issues using unicode magic like
this, but I guess it makes sense that the space in something like "layer 1"
would be non-breaking.
