[9.x] Use request isMethod instead of method comparison

[seriquynh]

Symfony Request class has a built-in method called isMethod to determine which HTTP method a request is. Using the method isMethod is a little bit nicer than method comparison.

use Symfony\Component\HttpFoundation\Request;

$request = Request::create('/', 'POST');

// Using isMethod looks a bit nicer.
if ($request->isMethod('POST') {
    // do something...  
}

// than method comparison
if ($request->method() === 'POST') {
    // 
}

All errors and failures in CI aren't related to these code changes. They're caused by testing setup environment (Eg, PHP version, extensions,...)

Not really. The skipped tests are due to the environment, but there is one test that is failing due to the request mock not being updated after this change.

There was 1 error:

1) Illuminate\Tests\Routing\RoutingRedirectorTest::testGuestPutPreviousUrlInSession
Mockery\Exception\BadMethodCallException: Received Mockery_130_Illuminate_Routing_UrlGenerator::full(), but no expectations were specified

/home/runner/work/framework/framework/src/Illuminate/Routing/Redirector.php:88

Feel free to mark as ready when tests are passing. Thanks

@X-Coder264 Thank you for figuring out the broken test! My bad! I've fixed it.
