[doc] Rewrite most frontmatters to Markdown titles
Completely throw away the frontmatter and only keep the title which is
turned into a Markdown title.
To recreate the rewrite, run the added script,
`util/rewrite_frontmatter.py`, in the root of the repo.
```sh
python3 util/rewrite_frontmatter.py ./
```
