Fixes the findings of the review of
#159.
- CI: "The workflow sets these:", so the four settings bind every
repo's workflow again.
- node and yarn: a stage that needs no yarn copies no `yarn.lock`
before it runs `script/bootstrap`, which is what the examples do.
- Dockerfile: names the stage to keep last, the one that ships.
- Version: "Without that check" replaces "Otherwise".
- The lists the review named are bulleted again, with the wording on
`next`. The submodule examples are in their own sentence, as in both
checklists.
