Subject: [PATCH] feat: publish linux/arm64 Docker images

Upstream's dockers_v2 migration (#540) did the heavy lifting, so
publishing arm64 images now only requires listing the platform and
providing emulation:

- .goreleaser.yml: add linux/arm64 to the dockers_v2 platforms; the
  release now pushes a single multi-platform manifest to Docker Hub
  and GCR.
- release.yaml: set up QEMU so the arm64 layers can be built on the
  amd64 runner.
- release-tests.yaml: likewise for the snapshot build, which builds
  one image per platform (tags suffixed -amd64/-arm64) without
  pushing.

Closes #531
