Open image inside notes in default image viewer

I think it would be a good idea if there a was another option in the context menu for the images inside to note that says `open in image viewer` that does open the image in default image viewer installed in the system

This is useful since its frequent that I want to zoom in the image, which doesn't seem to be possible inside notes, also other use-cases would be allowed.

I frequently save images inside items, and it would be very handy to preview the image in the sidebar. Or even thumbnails in the sidebar.
