Use a local registry for integration tests - #2295

Conversation
Replace ttl.sh with a local registry (registry:2 on localhost:5000) for publishing test buildpacks during the integration tests workflow. ttl.sh has been intermittently unavailable, causing the Tests workflow to fail when publishing multi-arch buildpacks. A local registry is started as part of the workflow, the buildpack is published to it with pack --publish, and the integration tests pull from it. This removes the dependency on ttl.sh while preserving the multi-arch publish path used for the composite java buildpack. Also disables Docker's containerd snapshotter and configures localhost:5000 as an insecure registry, mirroring the approach used in github-config.
