Updated documentation for tag sorting

I've updated the documentation where appropriate to reflect the new
changes introduced for the new tag sorting feature

Unfortunately, I was only able to update one of the two impacted
images (ss05.png). I don't have access to the pictured sample dataset,
so I'll have to rely upon the author to update the image for ss06.png themselves

Apologies for the 外人の日本語. 日本語上手ないですよ
