nvim: Add keymap to toggle rendering all images

By default we only render the image at the cursor. Should we want to
render all images instead we can now toggle this for image.nvim with
<localleader>pi.

To enable this we move the 'paste image' shortcut for prose formats onto
<localleader>pp instead.
