[Auth-UI][v10.0.0-[beta05] SMS quota rejection maps to NetworkException, phone auth shows "check your internet connection" instead of "used too many times"

Steps to reproduce

Request SMS verification repeatedly for one phone number until Firebase rejects it for quota.
Enter that number and tap send.

Observed results:

「認証エラー / ネットワークエラー。インターネット接続を確認してください。」 ( mean Please check your internet connection)
a network error, on a device with working connectivity. FirebaseUI iOS shows the correct 「この電話番号は何度も使用されています」(mean This phone number has been used too many times) for the same account state.

Expected results:

TooManyRequestsException, whose dialog message resolves to fui_error_too_many_attempts This is a string the library already ships translated in ja/ko/zh-rTW ("This phone number has been used too many times"). The correct copy exists and is simply unreachable.

Root cause:

Firebase reports SMS-quota rejection as FirebaseTooManyRequestsException, which extends FirebaseException notFirebaseAuthException.
AuthException.from only checks the ERROR_TOO_MANY_REQUESTS error code inside the is FirebaseAuthException branch, so the quota exception falls through to the catch-all is FirebaseException -> NetworkException. ErrorRecoveryDialog then renders fui_no_internet.

Is this possible to add FirebaseTooManyRequestsException -> TooManyRequestsException(...) before the is FirebaseException branch to fix this issue ?

                       ?: "Too many requests. Please try again later", 
        
                   cause = firebaseException
