Where should 'UV Examples' link?

[mialondon]

An area for possible confusion, and possible content update replication issues...

The page 'UV Examples' currently links to https://codesandbox.io pages.

But we also have https://www.universalviewer.dev/ (the latest dev build) and https://universalviewer.io (the current live version), and the difference isn't entirely clear.

Would it make sense to include the example manifests on the https://codesandbox.io pages on the dev and live demo pages, and update the links from the UV examples page?
