Minor bug: "Toggle edit/preview mode" command does not work for *.cook files

First, thank you for this plugin!

I noticed that command "Toggle edit/preview mode" does not work in a file with .cook extension.
However, the button for this command works as expected.

Ah, yes. That makes sense as this isn't a markdown view and therefore doesn't follow the same commands.
I wonder if there's a way I can tap into the existing command / hotkey... 🤔

If doable,
We should use Markdown to edit and cook lang to render / preview recipes. Export should support *.cook , .*html
