Non-constant time nonce comparison in Jenkins Microsoft Entra ID (previously Azure AD) Plugin

Jenkins Azure AD Plugin 396.v86ce29279947 and earlier, except 378.380.v545b_1154b_3fb_, uses a non-constant time comparison function when checking whether the provided and expected CSRF protection nonce are equal, potentially allowing attackers to use statistical methods to obtain a valid nonce.
