Upgrade all GitHub Actions to Node.js

24-compatible versions

Node.js 20 is deprecated on GitHub Actions
runners and will be forced to Node.js 24 on
June 16, 2026 and fully removed on
September 16, 2026. Upgrade all workflow
action references to their latest major
versions with native Node.js 24 support:

- actions/checkout: v2/v3/v4 -> v6
- actions/setup-go: v2/v4/v5 -> v6
- actions/setup-python: v2 -> v6
- peter-evans/create-pull-request: v3 -> v8
- DavidAnson/markdownlint-cli2-action: v16 -> v23
- docker/setup-buildx-action: v3 -> v4
- docker/build-push-action: v5 -> v7

Replace s0/git-publish-subdir-action
(unmaintained, still on Node.js 20 with no
update planned) with plain git commands in
the publish workflow.
