Given that these can only be added to the default org, we can probably put off some of the "polish" for these kinds until after the work for keyed multi-org capable provisioners is all done and feeling good. We should show them in the UI, and indicate what type they are, but other things can wait until later, which is what this issue tracks.

• Help tooltips describing the type of the provisioner and linking to the docs
• "Built-in" version indicator for built-in provisioners
