Reduced markdown report output - only failing scores

[BioPhoton]

User story

As a user of the CLI I want to have meaningful markdown reports.

The current markdown report includes categories if given as well audits. Especially in configurations with a lot of audits the markdown report is polluted with passing audits and categories. This makes it hard to find the important data and consume it.

The markdown report should only show failing audits and categories.

Acceptance criteria

• [ ] by default the markdown report should only show failing categories and audits
• [ ] if the flag --reporting.detailed is passed we display all audits and categories. Also passing ones.
