Following T307262: IP Info: Enable on watchlist, an event may now come from Special:Watchlist.
We need to:
- Add special_watchlist to this list in the schema: https://gerrit.wikimedia.org/g/schemas/event/secondary/+/58d7321ffcf59cf2b19740aa569585453a8aac7f/jsonschema/analytics/mediawiki/ipinfo_interaction/current.yaml#44
- Add a case for 'Watchlist' in the IPInfo log function: https://gerrit.wikimedia.org/g/mediawiki/extensions/IPInfo/+/ff53b118217020a2efb1c4f7e17226e0a52b188b/modules/ext.ipInfo/log.js#1
Question: should we also add a default case, say unknown, and add this to the schema, to prevent invalid event data being sent if this type of situation happens again? - No, we'd rather not fail silently
