doc: Build as CommonMark

We were using Pandoc’s Markdown parser. This is non-standard and might cause issues when we finally switch to some other tool.

Since RFC 0072 agreed on CommonMark, let’s switch to that.

We will use some extensions to make the limited syntax bearable but these are official so they should be more portable.
