[@capacitor/app] iOS: 'Expression implicitly coerced from String? to Any' warning in getAppLanguage

[dkalo97]

With @capacitor/app 8.1.1 on Xcode 27.0 (Swift 6.4), ios/Sources/AppPlugin/AppPlugin.swift produces:

Expression implicitly coerced from 'String?' to 'Any'

at getAppLanguage:

call.resolve([
    "value": Bundle.main.preferredLocalizations.first
])

preferredLocalizations.first is String?. Unwrapping it (e.g. ?? "en", or as Any if nil is intended) would silence the warning without changing behavior. Happy to send a PR.
