Cached images from Prismic

#### What would you like to be added:
Prevent Prismic images from being cached.

#### Why is this needed:
Currently, when an image is added or updated in Prismic, it doesn't immediately appear on the site. To make the updated image visible, we must redeploy the entire app. This somewhat contradicts the purpose of utilizing Prismic, which is meant to reduce the need for developer intervention in displaying data.

No file or test is named. Start by tracing the TypeScript image-rendering path that fetches Prismic assets and inspect how caching is configured. Done means an image updated in Prismic appears on the site without redeploying the app.
