Notifications posted on pull requests now carry a marker naming their
source, as an HTML comment on their first line, which is invisible when
rendered. When posting, 'ci-pages-notify.bash' finds its own earlier
notifications with the same marker on that pull request, and deletes them.
A pull request therefore holds a single comment per source, rather than
accumulating one per run.
The superseded comments are not lost entirely. Each notification carries a
one line summary linking its report, stashed in an HTML comment, and the
notification superseding it inherits that summary, together with the
history the superseded one held itself, into a collapsed 'Workflow history'
section. That section therefore lists all the earlier reports, stays flat
however many runs a pull request sees, and holds no entry for the report
shown right above it.
The 'pr-notification' artifact is now uploaded via the new reusable
'upload-pr-notification' action, which validates the content the reporting
scripts produced, and records the source key and the pull request number
alongside it.
