Merge Develop into Release (#3466)

* Added Onfido API token detection to recognize this type of secrets (#3463)

* PHP tainted-callable (#3464)

A callable is the name of a function, or an array with a class/object and a method. Basing these on user input makes it possible to call arbitrary functions.
