Add two tests, that we can extract images from public Google Drive links

[konard]

1. https://drive.google.com/file/d/1Cxkx6-428EQAX0-eiaq66H829ohnPp7q/view - here is a link, that should be extracted as image:

   

2. https://drive.google.com/file/d/1fgJaftjv53xCN7vgiJOaQlbfWkUqPgyd/view - here is a link, that should be extracted as image:

   

Also make sure the same urls without /view work.

So by default these urls should be converted to the images directly downloaded.

But if we have explicit request to markdown we should display content similar to the actual page in markdown with a link to image inside markdown document, we also might as well give full zip archive with both image and markdown document.
