Describe your changes

Docs update, preview user shouldn't require administrator access.

@tjheffner is attempting to deploy a commit to the Chapter Three Team on Vercel.

A member of the Team first needs to authorize it.

Oh sorry, I was just editing through the web ui and didn't notice. Hopefully resolved now!

Perfect! And good catch on noticing the additional Bypass content access control docs that needed updating.

The tests are failing now. But they aren't because of this PR. I'll fix them and then merge this PR. Thanks!

Is the requested change just asking that we use the readable names instead of the machine names exported in the config?
