Feature request: option to write styles as inline, or generate report as markdown

[mschmele]

I'm adding the report that's been generated to the $GITHUB_STEP_SUMMARY var, so it can be easily read in PRs. The table renders just fine, but any other styles or elements don't seem to play nicely. Is this something that could be done without too much trouble?

I didn't see any mention of this in the docs, but if I missed it feel free to point me in that direction 🙂
