### Current Behavior

When reading a file of a bucket with the Java AWS SDK the content-length is not set in the GetObjectResponse.

### Expected Behavior

The content-length is included in the response

### How are you starting LocalStack?

With a docker-compose file

### Steps To Reproduce

This is the content of my docker-compose file:
`  s3:
    container_name: "s3test"
    image: "localstack/localstack:2.2.0"
    ports:
      - "4566:4566"
    volumes:
      - ./src/test/local/s3/data:/var/lib/localstack/s3
      - ./src/test/local/s3/init-s3.sh:/etc/localstack/init/ready.d/init-s3.sh`

In the init script I create a bucket and put some file to it:
`awslocal s3api create-bucket --bucket test-bucket
aws s3api put-object --body /var/lib/localstack/s3/test.png --bucket test-bucket --key storage/test.png --content-type image/png --endpoint-url http://localhost:4566`

Then I query the file using the getObject Method of the S3Client of the Java AWS SDK


### Environment

```markdown
- OS: Windows 10
- LocalStack:2.2.0
```


### Anything else?

This behavior starts with version 2.2.0. Using version 2.1.0 everything works as expected
