Collection Thumbnails Not Displayed Correctly on Homepage After Adding Custom Logo, Thumbnail, and Footer Images

[ofahimIQSS]

Description: While testing GitHub Pull Request #10886 , an issue was uncovered regarding collection thumbnails on the homepage. After adding a custom logo, thumbnail, and footer image to a collection, the thumbnail fails to update and still displays the default Dataverse collection thumbnail instead of the uploaded custom one.

Steps to Reproduce:
Create a new Collection.
Navigate to Edit Collection > Theme + Widgets.
Upload a custom Logo, Thumbnail, and Footer Image for the collection.
Publish the Collection.
Navigate to the Dataverse homepage.

Expected Behavior:
The custom thumbnail uploaded for the collection should appear on the homepage, replacing the default Dataverse Collection thumbnail.

Actual Behavior:
The homepage still shows the default Dataverse Collection thumbnail instead of the custom thumbnail that was uploaded.

Environment:
Dataverse Version: v 6.4 (Demo)
Browser: Chrome

Note: This was not introduced as part of PR #10886 and happened sometime before that
