Refactor: Improve type safety in MixpanelFlutterHelper & Remove Plug… (#181)

* Refactor: Improve type safety in MixpanelFlutterHelper & Remove PluginRegistry.Registrar Usage

    - Remove PluginRegistry.Registrar Usage
    - Changed `toMap` method to use `HashMap<>` instead of `HashMap`
    - Changed `toList` method to use `ArrayList<>` instead of `ArrayList`
    - Changed Iterator to use `Iterator<String>` instead of `Iterator`
    - Changed List to use `List<Object>` instead of `List`

* Update Gradle configuration and dependencies

- Update `gradle-wrapper.properties` to use Gradle version 8.10.2.
- Update `settings.gradle` to use Android application plugin version 8.8.1
