Usage of deprecated `getConfigValue` method for iOS platform

Configuration Values > Accessing Configuration Values

For iOS, use the getConfigValue() method:

if let style = getConfigValue("style") as? String {
  // Set the style
}

What is missing or inaccurate about the content on this page?
Docs encourage use of getConfigValue method for iOS platform, but it has been deprecated in Capacitor 4.0.0-beta.0 here: ionic-team/capacitor#5495

Documentation should be updated for v4, v5 and v6 to use getConfig() method, I'd say there doesn't have to be a distinction between iOS and Android platforms

For reference I found a commits with migration getConfigValue -> getConfig in
