New helper for conditionally redirecting

[jase-languasco]

I'd like to suggest the addition of redirect_if and redirect_unless

It's possible it doesn't already exist because of the number of arguments that are required by redirect(), otherwise this feels like a good candidate for a new _if helper

If that were to be implemented into the Redirect facade, this could be implemented like Redirect::if()->to() and work like the optional() helper 🤔

[henzeb]

to follow conventions, it would be when / unless. which is is simply adding a Conditionable trait....

Great, couldn't be easier, then 👍🏻
