[mediawiki/extensions/WikimediaCampaignEvents@master] Setup tracking for CentralNotice banners experiment for WE2.1.5

https://gerrit.wikimedia.org/r/1213967

Change the story points as more details needed than the expectation, some still need clarification, it will launch in the coming January, we are here to prepare in advanced.

Thanks @hueitan for sharing a bit about tracking information via Slack. Continuing the conversation here, I have a few more questions:

• Based on the parameter you shared, does this mean that the URL will become https://ne.wikipedia.org/w/index.php?title=Event:Name_of_the_event&campaign=fy25-we215-banner
• Also, what will this URL help us track? Will it help us track which users came through the banner and what edits they made?
• If you look at the work-in-progress event page here, you will see that there are many links embedded on that page, articles linked directly to Content/Section Translation and the Visual Editor as well. I’m wondering if we should also append the parameter to those links if we want to track clicks on them, the edits made on those pages, and the users who made those edits and whether they were part of the campaign, or if this is something that can be tracked independently.
