### Is there an existing issue for this?

- [X] I have searched the existing issues

### Current Behavior

I am using the latest tag for the CI/CD process and today it started to fail because unit tests for the S3 provider that cover multipart upload throw the "Expected hash not equal to calculated hash" error on uploading a part. It worked just fine with the old version. The same unit tests work correctly with the real S3 provider as well.

And there is another issue. You fixed the https://github.com/localstack/localstack/issues/8392 bug that I reported previously but there is no version on Docker Hub that has that fix but does not have the new bug I described above. It seems that you rewrite the latest tag in Docker Hub which makes it impossible to rollback to the previous version.

### Expected Behavior

1. The upload part works without throwing an exception.
2. The previous versions of Docker images are available on Docker Hub.

### How are you starting LocalStack?

With a docker-compose file

### Steps To Reproduce

1. Initiate multipart upload with the correct MD5 hash.
2. Upload a part for which the hash was calculated.

### Environment

```markdown
- OS: Windows 11
- LocalStack: latest
```
