Integration of Amplify LocalStack Plugin with Amplify Gen 2

## Request for Compatibility with AWS Amplify Gen 2 Backend

**Is your feature request related to a problem? Please describe.**
Currently, this project works with the AWS Amplify CLI (Gen 1) as per the documentation [here](https://github.com/aws-amplify/amplify-cli). However, I would like to use it with AWS Amplify Gen 2 Backend.

**Describe the solution you'd like**
Please provide support for AWS Amplify Gen 2 Backend. This involves ensuring compatibility with the new backend infrastructure and updating the necessary scripts, configuration files, and documentation.

**Describe alternatives you've considered**
While it is possible to continue using Gen 1, the enhancements and improvements in Gen 2 offer better performance and new features which are beneficial for the project.

**Additional context**
Here is the link to the AWS Amplify Gen 2 Backend: [Amplify Backend](https://github.com/aws-amplify/amplify-backend).

Ensuring compatibility will help users transition smoothly to the latest version of Amplify, taking advantage of the new features and improvements offered in Gen 2.

**Suggested Changes:**
1. Update the configuration files to support Gen 2.
2. Modify the deployment scripts to align with the new backend structure.
3. Update the documentation to include instructions for setting up and deploying with Gen 2.

Thank you for considering this feature request.

Start by reviewing the existing AWS Amplify CLI Gen 1 integration, then compare its configuration and deployment scripts with the AWS Amplify Gen 2 Backend project linked in the issue. Define the required compatibility changes and document setup and deployment instructions; done means Gen 2 users can deploy successfully and follow the updated documentation.
