In #1833516: Add a new top-level global for settings.php - move things out of $conf allow_operations was moved to Settings() instead of Config().
We forgot to remove the config key from the Yaml file.
Updating schema config to reflect this change:#1912250-26: Complete configuration schemas for system module
Committed and pushed to 8.x. Thanks!
