Node-Vibrant Dependency Upgrade

Hey all, I am the maintainer of `node-vibrant`, which seems to be used in this project here:

https://github.com/adobe/leonardo/blob/main/docs/ui/package.json#L71

I just published a massively improved and stable v4 just now:

https://github.com/Vibrant-Colors/node-vibrant/releases/tag/v4.0.0

I was wondering if y'all wanted me to make a PR to upgrade the version you're using.

Best,

Corbin

Open docs/ui/package.json and inspect the node-vibrant dependency entry, then review the linked v4.0.0 release for upgrade details. Update the dependency only if the project still needs it, and confirm that the UI continues to work with the new version.
