Recovery Dependencies - Execute Receipe(s) on Recipe Failure

[ArchieAtkinson]

This PR adds the || syntax to the dependency system, allowing recipes to run on failure.

This is based on discussion in https://github.com/casey/just/issues/2583

Example:

# justfile
foo: || bar
  echo foo
   exit 1

bar:
  echo bar

# stdout
foo
bar

Please let me know if any additional work needs to be done or changes to the current behaviour.

One potential improvement that could be considered is passing the status code from the failing recipe into the recovery recipes
