Make sure that projects are ordered by increasing difficulty inside each project

I would like to work on this.

@laxmena Can you take a look down the ideas list and verify that they are already sorted? I think that they should be.

[laxmena]

Yes, they are, sorry!

Not available in the current formatting. I just tested and it's ordered by filename. So, astropy/aa.md will become before yt/aa.md and yt/aa.md will be before than yt/zz.md.

Maybe we could randomise such order, but that would need some javascript so it's not static once it's built. But... do we want to randomise all the ideas or just the projects they belong to and then sort them by difficulty?
