Add support for prerelease `13.332.0`

[felddy]

🗣 Description

This PR adds support for FoundryVTT v13 prototype.

Due to outstanding issues with NodeJS on Alpine Linux this container has been converted to a Debian-based image:

• 794

• https://github.com/felddy/npm-hang-test/issues/2

The switch to Debian leads to a change in supported platforms. This PR drops support for linux/arm/v6 and adds back support for linux/s390x which was removed as a workaround for #794.

Pre-installed distribution builds will now need to pass in their credentials using Docker Build Secrets. As similar implementation was suggested by @afwolfe in #1000.

Closes #1099 Closes #794 Supersedes #1000
