Handle several workflows

[gsmet]

In Quarkus, we have the documentation workflow and the Quarkus CI workflow and both can fail separately.

If only the documentation workflow fails, we are under the impression that things are OK as the report is green.

We need to fix that somehow. Either by aggregating reports for a given sha or by pushing separate messages (which might be easier but we need to handle things properly).

See quarkusio/quarkus#38430 (comment) for an example of this confusion.

This is now completed.
