Invalid type for Parameter::$schema according to phpstan

[nesl247]

API Platform version(s) affected: 4.1.7

Description
Phpstan complains that the type set for the $schema is invalid in the class Parameter. The problem is that phpstan does not support unions of array shapes. Thus anyone trying to use fields other than type or default in their array will get an error.

@param (array<string, mixed>&array{type?: string, default?: string})|null $schema

phpstan: Parameter $schema of class ApiPlatform\Metadata\QueryParameter constructor expects array{type?: string, default?: string}|null, array{type: 'integer', min: 1, default: 1} given.

How to reproduce

new QueryParameter(key: 'page', schema: ['type' => 'integer', 'min' => 1, 'default' => 1], constraints: [new Type('numeric'), new GreaterThanOrEqual(1)]),
