Improve the Contributors Section in Release Tiddler

[kookma]

Following to discussion here on Forum: https://talk.tiddlywiki.org/t/tw-5-2-3-is-getting-ready-to-be-released/3867/12?u=mohammad and few solutions I like to propose a minor improvement to Release tiddler

This solution has

1. A small modification to contributor macro by adding a dive
2. Adding few css to use flex section with 80x80px children
3. Use a $list widget to sort and display contributors
4. The $list uses sort, so no matter how to add contributor names
5. It is possible to use a tiddler or a field to keep the list of contributors, here I used a variable...

To give a try download Contributors - ii.zip and unzip and drag and drop to https://tiddlywiki.com/prerelease/

Tested on a separate tiddler on https://tiddlywiki.com/prerelease/

@Jermolene - if you like the solution let me to submit a PR. The solution is customizable and adds few bytes to Release tiddler
