Move routes to dedicates routes file

[driesvints]

Passport is probably one of the oldest first party package we have. It still uses the old way of setting up routes through a dedicated routes method on the Passport class. It's best that we move it to a new routes/web.php file in similar fashion as all the other first party packages.

I second this. I have installed laravel passport very recently and have no idea what the endpoints to begin with and cannot write my api documentation

Will land in Passport v11
