feat: Display maintainers annotation

The annotations are displayed inside the check collapsible component, after the reason and details, as "Maintainers Annotation". Then, we list the human-readable annotations for that check based on the label annotations given by the maintainer in scorecard.yml file.

(For this field to come, first the JSON output in ossf/scorecard needs to introduce the maintainers annotation field).
