[make:auth] Adapt command to use the upcoming LogoutRouteLoader #1375
Description
This PR has been merged a few days ago : symfony/symfony#50946
We now don't need to make a controller to match the logout path, we just need to register a route loader that deals with loading a route for each firewall that has a logout.path.
It would be nice to have this change reflected in the make:auth command.
I've started to work on this, but I'm not sure if there are any plan to release a new version of the maker-bundle with minimum compatibility with symfony 6.4 / 7, or if I should test if the new LogoutRouteLoader service exists and change the behaviour accordingly.
