As a user, I want to see the Item's image (P18) in the searchbox results in order to more easily identify the one I want.

The new Vector-2022 skin is also on Wikidata using the new Codex TypeaheadSearch (T316093). That search shows thumbnails of the page's image by default. Though we currently disable that config option, because that information is currently not provided by wbsearchentities.

Problem:

Example:

Screenshots/mockups:

BDD
GIVEN
AND
WHEN
AND
THEN
AND

Acceptance criteria:

Open questions:

• Can we add tracking for how many search results that are being shown actually have images? Maybe, if only 1% or so of the search results have images, we prefer not to show them at all, instead of almost always only showing the empty placeholder?
• We should consider if we can do something similar for T140131

Notes:

• Showing the placeholders on Wikidata was disabled in Wikidata: don't show Vector search thumbnails (Ic28029dc)
• "page image" in the page-information: https://www.wikidata.org/w/index.php?title=Q42&action=info is determined via wmgWBRepoPreferredPageImagesProperties in InitialiseSettings.php -- we probably want to make use of that
