Bug, feature or question?

Is this a bug, a feature request or a question?
Give us a short description.

The property Hybridauth\User\Profile::$identifier is typed with phpdoc as int|null but the actual returned value is a string. This gets in trouble with php linters.

Version and provider

What version of Hybrid Auth does this relates to?
3.8

Is this an issue with a provider? If yes, which one?
Found this while working with the google provider only.

Reproduction

How can we replicate this issue?

$hybridauth = new Hybridauth($config);

$adapter = $hybridauth->authenticate($providerName);

$userProfile = $adapter->getUserProfile();

$userProfile->identifier; // will return string

good catch. I think we can try to extend the type for this field. So, at then end it will be string|int|null
