YAML front-matter is currently only used for Vitepress.
Because of that, to avoid confusion, we can remove this YAML
front-matter when converting the Markdown in packages/mermaid/src/docs
to go into the `docs/` folder for GitHub browsing.
Add the auto-generated header after any YAML front-matter blocks.
YAML front-matter is normally only valid in Markdown when it's at the
beginning of the Markdown file. GitHub/Vitepress may otherwise render
it incorrectly.
Change the `transformBlocks` function, which transforms a markdown str,
and instead making it into a
`transformMarkdownAst` function, which transforms a Markdown AST.
This means we can use the remark/unifiedjs plugin infrastructure, see
https://unifiedjs.com/learn/guide/create-a-plugin/
Vitepress uses YAML frontmatter to configure Vitepress specific
settings, see https://vitepress.vuejs.org/config/frontmatter-configs
We just need to use `remark-frontmatter` to add support for it.
GitHub also renders the YAML front-matter nicely in a table
automatically, but maybe we should instead strip it, if it's only
used by Vitepress?
