Support multiple Docker image architectures

[dtcooper]

Support for at least arm64 Docker container would be fantastic! This could be done by modifying the GitHub action. If there's interest and any support for this, I could submit a PR.

Yes, that would indeed be great. PR very welcome!

We are using https://github.com/esatterwhite/semantic-release-docker to build the Docker image. Since a few days it finally supports multi-platform builds! 🥳

I made some quick changes here. Sadly the run failed: https://github.com/peers/peerjs-server/actions/runs/8513000291/job/23315788634

You can probably take it from there. Thank you for taking this on!
