ci: bump checkout, setup-node, and setup-python to v7 (#28)

Update every reference in the four workflows. The v7 changes are safe here because checkout's fork PR protection does not affect this repository's push, pull_request, workflow_dispatch, or pages-deploy workflow_run usage; setup-node and setup-python keep the Node 24 runtime, and this repository uses neither changed cache behavior nor setup-python's removed pip-install input.
