[11.x] The health route should be loaded even when there is a model binding at the root

[xiCO2k]

This PR makes sure the health endpoint loads even if there is a model binding on the root:

Example

// routes/web.php

use Illuminate\Support\Facades\Route;

Route::get('/{user}', fn () => response('', 404));

before this PR it will load the /{user} route before the health.
