Expected: there's no error for code that imports type SerializableError

Actual:

ERROR: [InvalidTypeImport](https://psalm.dev/233) - 34:25 - Type alias SerializableError imported from ExecutionResult is not defined on the source class

/**
 * @internal
 *
 * @phpstan-import-type SerializableError from ExecutionResult
 */
class Foo
{
    /**
      * @return SerializableError
     */
    public function format(\Throwable $error): array
    {
        return [
        'message' => 'message',
    ];
    }
}
