Flag the type of codeblock for conversion between markdown and html. Sometimes markdown-it will place the attribute on <code>
and sometimes it will place it on <pre>
that's the behavior of markdown-it.
import CodeblockType from "markdown-it-codeblock-type"
import MarkdownIt from "markdown-it"
// --
renderer = new MarkdownIt()
renderer.use(
CodeblockType
)
