Added blog_posted_by_hint to index to indicate author right on home page

First of all, thanks for the excellent package!

I added a feature to my own personal repository, and I thought that it might be a nice addition to the tool overall.

I felt that it would be great to have an indicator right on the home page to show who was the author of the blog. So, I added a line to show it. Here is how it looks like, visually speaking:

Of course, I'm not completely sure if this is a feature that is truly good to have on this tool, and I'm also not sure if my HTML is correct (I'm not a frontend dev and I know HTML is more complicated than it looks lol), so please, let me know if you want me to do any corrections/further explanations
