[mediawiki/extensions/IPInfo@master] Enable IPInfo on Special:Watchlist

https://gerrit.wikimedia.org/r/787882

@Niharika @Tchanders There might be some changes to make this work for Eventlogging. For example, opening a popup in Special:Watchlist we send the event:

{
  "$schema": "/analytics/mediawiki/ipinfo_interaction/1.2.0",
  "event_action": "open_popup",
  "event_context": "page",
  "event_source": "Watchlist",
  "user_edit_bucket": "1000+ edits",
  "user_groups": "ipblock-exempt|sysop|*|user|named|autoconfirmed",
  "event_ipinfo_version": "full",
  "meta": {
    "stream": "mediawiki.ipinfo_interaction",
    "domain": "en.wikipedia.beta.wmflabs.org"
  },
  "dt": "2022-05-04T11:02:10.302Z"
}

With event_source: "Watchlist. I don't know if that is correct. There may be other changes we need to make as well.

Thanks @dom_walden - have created T307594: Add special_watchlist to possible event_source values on ipinfo_interaction EventLogging schema

I now see IPInfo popups on Special:Watchlist.

I tested it for several different settings of the Special:Watchlist page (which you can see when you go to the Watchlist tab in Special:Preferences. e.g. normal vs. enhanced vs. "non-Javascript" interface).

I tested that it worked for Live updates in normal and enhanced mode.

For those I checked, the revision ID IPInfo was looking up corresponded to the revision ID of the entry in Special:Watchlist.

I briefly tested it in RTL in normal and enhanced mode.

As I understand it, Special:Watchlist shares a lot of the same functionality as Special:RecentChanges. If it works on the latter it should work on the former.

I found a small UI bug, but doubt it is important T307659.
