Expose DeploymentBucket in overrides.ts

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

storage, hosting

### Is this related to another service?

S3

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

https://docs.amplify.aws/javascript/tools/cli/project/override-iam/

Per this documentation, it is only possible to override the amplify-generated IAM resources at the project scope. This aligns with the exposed interface in
https://github.com/aws-amplify/amplify-cli/blob/dev/packages/amplify-cli-extensibility-helper/src/types/project/types.ts

It would be really nice to be able to override configuration of the Deployment Bucket using the same mechanism

### Describe the solution you'd like

DeploymentBucket exposed in overrides.ts

### Describe alternatives you've considered

In order to be able to modify the properties of the bucket, we are relying on external modifications outside of amplify
