FE: Add new multiples token: "Multiple fee/fine charges" for the Fee/Fine Charge section

Purpose: Add a new multiples token for the Fee/Fine Charge object, called "Multiple fee/fine charges", to the Add token modal in the patron notice template configuration.

NB: The behaviour of this new token, should be similar to the other multiples token: Multiple loans (e.g. the behaviour when adding the token into the Body).
