### Is there an existing issue for this?

- [X] I have searched the existing issues

### Current Behavior

When using the latest docker image, if we define a local secondary index for a dynamodb table and query it, localstack fails with `Index Not Found`

This behaviour is not seen in the previous version of the docker image 0.14.2. I believe this was introduced in a recent change from https://github.com/localstack/localstack/pull/5799

### Expected Behavior

Querying local secondary index should be supported like it previously was

### How are you starting LocalStack?

With a docker-compose file

### Steps To Reproduce

#### How are you starting localstack (e.g., `bin/localstack` command, arguments, or `docker-compose.yml`)
docker-compose.yml
```
services:
  localstack:
    image: localstack/localstack:latest
    ports:
      - "443:443"
      - "4566:4566"
      - "4571:4571"
    environment:
      - SERVICES=dynamodb,cloudformation
      - DEFAULT_REGION=eu-west-1
      - START_WEB=false
```

cloudformation-template.yml
