Provide setting or option for route middleware display using artisan route:list.

[vincent-w2w]

Recently the output format of artisan route:list has been changed (7ebd211), which changed the output for routes that only reference route groups in their middleware spec from a concise list to an aggragation of middleware in those groups, leading to messy output for routes with a lot of middleware.

I could not find a reason for this change in the discord, but I do appreciate that this will fix issues for some people. However, as this change made this command pretty much useless to my usecase, I would propose an option or setting to be added to switch between shorthand and full route middleware descriptions.
