Instrument clicks to items in the image browser

Description

One way of doing this would be add the data-event-name HTML attribute to carousel images

The WikimediaEvents MW extension serves as a bridge between the image browser and A/B tests. It expects a specific HTML attribute to track clicks on relevant elements.
It doesn't seem compatible with Vue, and a simple attempt to hardcode the attribute in a HTML template didn't work.

T402020#11126056 provides an initial investigation.

Acceptance criteria

  • Define a Vue plugin that introduces event listeners for a given component
  • Add the data-event-name HTML attribute in CarouselItem's HTML template

Is just the presence of the 'data-event-name’ sufficient, or should the Acceptance Criteria also include that click tracking for that element also works?

We will need more than just the data attribute in order for this to work correctly, since Vue adds and removes pieces to the DOM after the initial page load.
