Deploy release artifacts (SLC) in S3 Buckets

[tomuben]

Background

Currently we deploy the release artifact on Dockerhub and upload them to the GH release page.
However, GH has a restriction that artifacts for a release must not exceed 2GB. Currently the cuda container exceeds this limit.
It makes sense to deploy the container also in a release S3 bucket, which should be public-readonly. The GH release should then also link to the respective folder in the bucket.

Acceptance Criteria

1. Create a new S3 bucket for release stacks which are public-readonly
2. Upload release script-languages-contaienr there
3. Optional: Find a way to automatically mention the S3 bucket in the GH release
