"Spoilers differ from airbrakes in that airbrakes are designed to
increase drag while making little change to lift, while spoilers
greatly reduce lift while making only a moderate increase in drag."

I had always used the terms spoilers and airbrakes interchangeable.
This statement makes it seem like they are not. So what does the
typical sailplane have? Spoilers or airbrakes?

Oh boy!

According the the original Glasser-Dirks owner's manual for a DG100G,
the sailplane has "spoilers".
