Set up API router when first API routes are generated

[nicodevs]

Issue

In a clean installation of Laravel 11, the routes/api.php file is absent and not configured in bootstrap/app.php. When Blueprint generates API routes, it creates the file, but the developer must manually edit it to add the PHP opening tag and the use Illuminate\Support\Facades\Route; line. They must also modify bootstrap/app.php to enable that API route file.

Changes

This PR updates Blueprint to check the following when creating API routes:

• Ensure the routes/api.php file exists, creating it if necessary, using a basic stub
• Ensure the API routes file is configured in bootstrap/app.php, adding the configuration if missing

These actions occur before the addition of the generated API routes.

This PR takes inspiration from Laravel's ApiInstallCommand.

Testing

Tests to check this functionality has been added to RouteGeneratorTest.php.

PS. No annoying WIPs this time! 😅

The tests are failing, but they are unrelated to this PR and should pass after this is merged: #729

I merged the other if you want to rebase this.

Thanks @jasonmccreary ~ Done!

I'm surprised this \n passes on Windows...

It is the hardcoded return value we mock, so it will work (a PHP_EOL would have been better though). However, that part is not entirely necessary, so I streamlined the check here: #730

Good PR. There are a few areas that concern me. I commented on the test. But along the same lines, it'd be nice if this had more of an integration tests where it actually changed an existing bootstrap/app.php file.
