Provide suggested track of katas

[tomhostyn]

The overview.md starts with the bad-commit kata, which is more advanced than the basic-commits, basic-staging, basic-branching.

It would be helpful if a learning path from easy to hard were provided

Thank you Tom,
when I saw your issue I actually thought that you just had missed it, because in my mind - I had already put a learning path in the repo. It does however seem like you are right. I will amend this issue.

It is important that people are able to figure out where to start and how to progress.
I tend to not notice this because I use the katas in guided classroom sessions.

Cheers!

This is also kind of covered by #56 , my thought is there could be a

• Basic Git
• Manipulating Git + Internals
• Configuration
• Workflows

Or something like that
