docs: Add missing notification keys (#832)

Sounds Enabled and Alert Type were missing, and although there's
probably no MDM using the 'spec' order, re-ordered for easier
maintenance if you're diff'ing the
mdm/profiles/com.apple.notificationsettings.yaml in
github.com/apple/device-management
The 'Banner' designation for Alert Type matches what's in the GUI and
maps to integer 1 (==Temporary) but Apple has a discrepancy with what
you see in the DDM-applied MDM profile vs the Notifications GUI config
interface in System Settings as of a bit ago
