Tweak GitHub workflows for docsite additions (#224)

- Rename `lint` to `analyze`, merge `audit` step into it
- Ensure all steps use `ubuntu-latest`
- Re-run `analyze` when a PR is reopened
- Upgrade `checkout` and `setup-node` to latest versions, removing
warnings
- Rename `all` to `ready-to-merge`
