feat: add toast.warn() function

[JosteinKringlen]

I saw a couple of comments regarding extending toast with warn and info, and thought I'd give toast.warn() a go :) The warn fn works the same way as error and success, and will by default render a toast with a yellow+black icon for 3 seconds.

I'll probably also take a look at toast.info() after I'm done with warn :)

See #29
