Upgrade to Node 20 on CI, enable actions cancellation (#24524)

- Upgrade node, the
[snap](7abe958f5b/snap/snapcraft.yaml (L47))
is excluded from this because [there is no Node 20 snap
yet](https://snapcraft.io/node).
- Add actions build cancellation based on
[this](https://docs.github.com/en/actions/using-workflows/workflow-syntax-for-github-actions#example-using-a-fallback-value).
