[11.x] Add Conditionable Trait to Request

[ahmeti]

Just like in the Query Builder class, we can use the when method in the Request class.

/**
 * Prepare the data for validation.
 */
protected function prepareForValidation(): void
{
    $this->when($this->input('account_id'),
        fn (Request $req, int $accountId) => $req->merge(['account_name' => Account::getName($accountId)]),
        fn (Request $req) => $req->merge(['account_name' => null])

    )->when($this->input('contact_id'),
        fn (Request $req, int $contactId) => $req->merge(['contact_name' => Contact::getName($contactId)]),
        fn (Request $req) => $req->merge(['contact_name' => null])
    );
}

	$value = $value instanceof Closure ? $value($this) : $value;

	return new HigherOrderWhenProxy($this);
	}
	if (func_num_args() === 1) {

Why not add the Illuminate\Support\Traits\Conditionable trait?

Thank you @rodrigopedra, good catch! Updated.
