Use string for example

In the docs [here](https://apidock.com/rails/v6.0.0/ActiveSupport/MessageVerifier) under the `Making messages expire` section, it was a little unclear what is `doowad` & `parcel` which ideally be a +string+ or a variable but in the complete documentation, we haven't used the reference of any variables except +token+, so these 2 should be a string.
