Read 250.122(B)So we pulled a 10 gauge hot and neutral, but we pulled a 12 gauge ground. We upsized to 10 gauge for voltage drop, but why don't we upsize to 10 gauge for the ground wire? thank you.

You should have used a 10 equipment grounding conductor.
yup.So even if it's a 20 amp breaker protecting the 10 gauge wire?
Someone could could come along and see #10 and say, "Hey, we can throw in a 30a breaker."So even if it's a 20 amp breaker protecting the 10 gauge wire?

Make your circuit a 30 - 60 amp feeder and you still only need a #10.
Just to clarify the overcurrent protective device must be 30-60 then you can use the #10 equipment grounding conductor. If you upsize the conductor and kept the overcurrent protective device at 20 then you would have to upsize the equipment grounding conductor to whatever size the conductors may be.
