[Form] Autocompletion using named parameters

[SVillette]

Description

In a controller, when a form is created with createForm method, the autocompletion of the form options is triggered when using the third parameter of this method

$form = $this->createForm(FooBarType::class, null, ['method' => 'GET']); // "method" option was suggested with autocompletion

But when using named parameters, the autocompletion is not triggered.

$form = $this->createForm(FooBarType::class, options: ['method' => 'GET']); // Autocompletion does not work
