feat: derive Get Directions link in locator from ref_listings if present

[mkouzel-yext]

Updates the locator to derive the Get Directions link on result cards from the ref_listings field in the search response if present, otherwise fallback to the yextDisplayCoordinate. If that is also not present, don't display the get direction button.

Copies the logic in #846 to determine the URL.

J=WAT-5136
TEST=manual

Created a locator in the Krusty dev account (514581), which has some entities with ref_listings data pointing to simulated URLs. Confirmed that when the ref_listings field in the search response had a listingUrl for a GOOGLEMYBUSINESS publisher, the Get Directions button pointed to the listingUrl rather than the Google Maps one generated from the yextDisplayCoordinate field. Confirmed that when the ref_listings field was empty or did not have a GOOGLEMYBUSINESS publisher, the yextDisplayCoordinate field was used to generate the Get Direction URL instead.

Walkthrough

The Locator component's directions link generation has been refactored to use a getDirections utility function instead of a hard-coded Google Maps URL builder. The new implementation prioritizes building directions URLs from location listings when available, falling back to coordinates if needed. The Location interface has been extended with an optional ref_listings field of type ListingType[] to support this functionality. The component now imports getDirections and ListingType from the @yext/pages-components package, replacing the previous inline implementation.
