Zeebe s390 Architecture Support

We want to deploy zeebe on s390 architecture servers. While browsing this github issue I get an idea that supporting a different architecture requires some changes to the build pipeline.

Since we need to build these docker images quickly, could you please guide us on how to build s390 architecture images locally - would modifying the Dockerfile be enough (if so please guide us on the modifications needed)? Would we need to raise a github issue requesting to add support?

Thanks.
