Adapt iD POI import script to iD changes
In the scripts directory we have a GJS script to import definitions for POIs to a JSON file that Maps uses (including translations). Recently there's been changes upstream:
- This information has moved from https://github.com/openstreetmap/id to the https://github.com/openstreetmap/id-tagging-schema project, we should update the README in scripts/ to reflect this
- There might(?) be other changes to the layout/format relative to earlier when it was included in iD itself that might requires changes to our script.
