✨ Extend UPath.to_url() to private paths

[sheetalgiri]

Why

Agents trying to create markdown with images that are artifacts but this doesn't work well because it refers to local paths of the image https://lamin.ai/laminlabs/lamindata/artifact/6bWK22v0wFFOc5gF0000

Solution

Add functionality to create such a link using artifact.path.to_url(). Closest thing that existed before was ln.Artifact.path but this does not create a proper link. The implementation closely follows the implementation in LaminHub for the same :https://github.com/laminlabs/laminhub/blob/6f213282d58707ecbd86ba896b4ebab78851c03b/frontend/src/lib/utils/utils.ts#L44-L69, except that the /storage/s3 endpoint can only be used if the instance is on LaminHub, so this is being checked for.
