nvim: Add optional snacks.nvim dependency for updated molten-nvim

Since the molten-nvim plugin supports setting `snacks.nvim` as
`molten_image_provider`, we add it as optional dependency.

It is _not_ enabled yet however, have to figure out how to accomplish
this from the embedded optional spec, and also fix molten-nvim before
adding more stuff to it.
