Steps to replicate the issue (include links if applicable):

• On 17 January 2023 two Wikidata items were merged, {{Q|50950479}} was merged into {{Q|12407075}} .
• Three Commons files had {{Q|50950479}} in their tab Structured data:
  • [[c:File:Kodomo no kuni magazine, art submissions from children, vol. 2 no. 9, September 1922.jpg]]
  • [[c:File:Minha família em formato Kiss.jpg]]
  • [[c:File:Meridiaantunnel close-up.jpg]]
• After the merge, these three Commons files had still the old Wikidata item in their Structured data instead of the new one.
• In {{Q|50950479}} there were no links to those files via "What links here".
• I have changed those Commons files manually, so now they have the correct Wikidata item in their tab Structured data.

What happens?:
The files with the Wikidata item {{Q|50950479}} have not been changed automatically with the merge of the Wikidata items.

What should have happened instead?:
When a Wikidata item has been merged into another one, the Commons files with that Wikidata item in the tab Structured data should be changed automatically, so that the new Wikidata is now in the tab Structured data instead of the old one.
