Run subsequents on success or failure

Relates to: https://github.com/casey/just/issues/819

It looks like recipe_1: || recipe_after_1 wasn't implemented. I was wondering if a feature like that could be added?

My use case would be to have a common setup and cleanup recipe I can add to other recipes. It also allows the cleanup recipe to run regardless and avoid prefixing everything with a dash.

Amazing tool by the way :)
