CONTRIBUTING.md told authors to write `Depends on #N` in the
description, but the pr-template rule in tools/check_conventions.py
only accepts the checklist line `Depends on: #N` or `Depends on: none`
from the pull request template. A pull request that followed the
document failed the Conventions job with "fill Depends on with #N or
none". The sentence now shows the checklist form.

Authors with no merged pull requests can have 1 open, with at least 1
merged 20, and from 20 merged there is no limit. Reopening a pull
request runs the check again.
