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 :)

Read the related issue #819 first, then trace how just executes recipes and handles success or failure. The feature should allow a recipe such as `recipe_1: || recipe_after_1` to run the subsequent recipe regardless of the first recipe's result, supporting shared setup and cleanup without prefixing commands with a dash.
