Does apple have a usb-c to usb adapter?
Sure, but it wouldn't really make that much sense just to charge and that would probably limit the charge current since it's USB-A. It really wouldn't help much if your intent is to just use that cable, because it would just revert to USB-A performance - I'm thinking 5V at maybe 2.4A?
For your application it should be fine to get a longer aftermarket USB-C to USB-C cable using the 20W Apple power adapter that came with your iPad Pro. I have a few 6 ft and 10 ft USB-C cables (rated for 5A current) marketed by Monoprice. I got them at a pretty good price (usually under US $5 on Amazon) but the price varies (and can be volatile) based on the color. I prefer the Monoprice Stealth. They have several options including standard 3A (should be fine for an iPad Pro) and 5A.
