feat: switch from rage to age

Why
===
* Someone said age works better with password protected keys,
requiring entering the password less often.
* We switched to rage from age in
07ce686
because it was limiting recipients to 20. This was fixed
FiloSottile/age#139

What changed
===
* Switch from rage back to age (the reference implementation) in all
the spots
* Update the docs to show how to switch back to Rage
