Restore feature states requires restricted permissions

[stefnestor]

👋 howdy, team!

This

• adds in the two most common errors encountered when snapshot restoring feature states / system indices wrong
• cross-links how to get the needed restricted permissions to restore system feature states (and removes outdated-since-v8.0 information which no longer works)
• adds in an example API outline of reading the feature state to its snapshot appearance to determining which to restore

Related changed pages

• Snapshot and restore > Feature states
• Restore a snapshot > Restore a feature state and Restore an entire cluster
• File-based access recovery
