docs: How should I spell check Asciidoc or Markdown files with this package?

Description

Not sure if that is possible, but could I also use this package to spell check documentation written in Asciidco or Markdown format?

I think it should work with Markdown, but I am not sure with Asciidco. Additionally, you could always try to convert your docs to plain text and then check it.
