Add list of re-written software in line with the rewrites.bio principles

[VishnuRaghuram94]

There is one example (rustQC) on the site but it would be useful to have an easily accessible list of software that are in line with the principles

Thanks for the suggestion @VishnuRaghuram94! In the first draft of rewrites.bio I had exactly this, but I removed it as I was worried that it might lead people to squabble over what qualified and what didn't 😅

Several people have asked for this though, so I'll leave the issue open for now. Maybe we can bring it back in some form, either here or somewhere else (and point to it there or something).
