Need to add check that skipOpenUrlForFirebaseAuthBlockSwift was already added into AppDelegate.swift.

[aivanychev23]

This implementation

react-native-firebase/packages/auth/plugin/src/ios/openUrlFix.ts

Line 186 in c1a1532

return contents.replace(pattern, `${fullMatch[0]}${skipOpenUrlForFirebaseAuthBlockSwift}\n`);

has an issue when same block skipOpenUrlForFirebaseAuthBlockSwift added multiple times into AppDelegate.swift when
npx expo prebuild command executed.

Need to replace on

if (!contents.includes(skipOpenUrlForFirebaseAuthBlockSwift)) {
        return contents.replace(pattern, `${fullMatch[0]}${skipOpenUrlForFirebaseAuthBlockSwift}\n`);
}
return null;

to fix this issue.
