Fix: Remove unused Plugin registration using Android embedding v1

Description

This PR comments out the registerWith method, which was using the deprecated Android embedding v1 API. The method was causing a compilation error due to the removal of PluginRegistry.Registrar in Flutter.

Issue
• The build was failing with the following error:

error: cannot find symbol
import io.flutter.plugin.common.PluginRegistry.Registrar;
                                              ^

•	PluginRegistry.Registrar is no longer available in Flutter’s modern embedding API.

Solution
• The unused registerWith method has been commented out to prevent build failures.
• This aligns the plugin with Flutter’s latest Android embedding v2 requirements.

Testing
• Verified that the plugin builds successfully without errors.

Let me know if you need any modifications! 🚀
