Change link pointing for 'more assets' button in events page

[web3kitty]

Example event page: https://web3privacy.info/event/m25rom

At the bottom the 'more assets' button leads to a related page within the gen-img functionality within the website: https://web3privacy.info/gen/event/?id=m25rom

This gen-img function is planned to be phased out and will be replaced by some standalone solution outside of the /web codebase. This is an issue to track that the url for this 'more assets' button actually points to the correct folder within the /data github repository: https://github.com/web3privacy/data/tree/main/src/events/_images/{YEAR}
