(gen2-migration) `interactions` category

### Is this feature request related to a new or existing Amplify category?

_No response_

### Is this related to another service?

_No response_

### Describe the feature you'd like to request

Add support to the migration tool for the [interactions category](https://docs.amplify.aws/gen1/react/build-a-backend/more-features/interactions/set-up-interactions/). This includes both code generation and refactor.

### Describe the solution you'd like

We are going to use [cdk-from-cfn](https://github.com/cdklabs/cdk-from-cfn) in order to generate CDK code that we will then hookup into the amplify backend using `backend.createStack('interactions')`.

### Describe alternatives you've considered

None

### Additional context

This is how amplify recommends setting up interactions in Gen2 manually: https://docs.amplify.aws/react/build-a-backend/add-aws-services/interactions/

We can use as reference to review the cdk-from-cfn generated code.

### Is this something that you'd be interested in working on?

- [ ] 👋 I may be able to implement this feature request

### Would this feature include a breaking change?

- [ ] ⚠️ This feature might incur a breaking change

Start with the cdk-from-cfn project and the linked Amplify Gen2 interactions setup; trace how generated CDK would connect through backend.createStack('interactions'). Done means the migration tool supports both code generation and refactoring for the interactions category.
