feat: implement new default monospace font Geist Mono (#22081)

This pull-request follows up #22060

Felt wrong to only make use of Geist when there is a Monospace variant
here too. Felt best we default to this as the default font as its inline
with the rest of the application. This also updates the lower line for
Workspace Statistics 🙂
