Arne Huang bb4078f78b Pin actions/checkout to a commit SHA
Follow-up to #838: actions/checkout was the only third-party action
left on a mutable ref (@master). Pin it to v6.0.2's commit SHA, matching
the pattern used for docker/setup-qemu-action, docker/setup-buildx-action,
and docker/login-action.
