Address links: Add geofield token support for public transport links

Problem/Motivation

The address-link-module allows to use the geofield-token only in the Field "Directions service base URL" but not in the Field "Public transport base URL".

Steps to reproduce

Try to add the token [geofield:latlon] in the Field "Public transport base URL" at `/en/admin/config/content/openculturas_address_links`. Open a location and click or hover on the Public Transport Link. The geocoordinates won't show up in the URL.

Proposed resolution

add the geofield-tokens or remove them from the list of useable tokens.
