Note on using cider

[Risto-Stevcev]

Newbie note:

The create-tauri-app command will ask what your dev command is (default is npm run dev).
Adding a command there will include it "beforeDevCommnad" in tauri.conf.json, like this:

    "beforeDevCommand": "npm run dev",

I had to remove this command to get it to work. Then I would just do npm run tauri dev, which waits for localhost:3000 to start up, at which point in emacs I would run cider with M-x cider-jack-in-cljs, then select shadow, and then the :app build, and then it works.

I think it would be useful to add a note somewhere in the readme for noobs like me.
