[Request] Build each sample in a separate CI job

Describe the feature

Potentially handy reference for generating the matrix: https://stackoverflow.com/a/76413829

I imagine this could be used to basically fork a separate Job for each of the build.bash files found in the repo, other than the one at the project root. All of these can simply be executed by a separate runner so that the containers get built and pushed by independent jobs in parallel.

Anything other information?

Another enhancement: use the same technique as cryostatio/cryostat#786 to build for amd64 and arm64 on separate runners as well, and merge the results into a multiarch manifest.
