improve the Application::bootstrapWith hook to find Laravel's application name

[joke2k]

Description

As per #3034 this fixes the scenario in which a Laravel 11+ application does not have the config/app.php file and when in this file is not specified the "name" key (using the default from vendor/laravel/framework/config/app.php).

I was trying to cover my code with test but I cannot execute the test suite, it cannot execute some build using make due to lack of permissions 🤷‍♂️ .

The new behaviour from Laravel config loader is here: https://github.com/laravel/framework/blob/11.x/src/Illuminate/Foundation/Bootstrap/LoadConfiguration.php#L189

This is the default config:
https://github.com/laravel/framework/blob/11.x/config/app.php#L19

Fixes #3034
