refreshAccessToken() wrong return type

[victorlapshev]

It seems like method refreshAccessToken of Infusionsoft\Infusionsoft have incorrect return type declared in doc block.

    /**
     * @return array
     * @throws InfusionsoftException
     */
    public function refreshAccessToken()

But it returns Token object.

        return $this->getToken();

...

     /**
     * @return Token
     */
    public function getToken()
    {
        return $this->token;
    }

This could be a problem for code static analyse tools, like psalm or phpstan.
