Make the "small" icon smaller

[vbagirov]

Many users still find the current "small" icon too big. Consider renaming "small" icon to "medium" and adding an even smaller one (reference -- "small" icon from the previous Assistant version).

Here's the size I suggest:

It looks like new icon size is the same as previous.

Yeah, it'll still appear big if the Assistant is cached in the browser cache. Clearing the browser cache fixes it and it looks nice and small again (though blank in Edge/Firefox, which is a different issue).
