Follow-up issue #6761.
In this PR, I have updated the download API under monai.bundle to support model zoo NGC hosting.
It appears that there are still several other methods that need to be updated, such as get_all_bundles_list, get_bundle_versions, and get_bundle_info which may be used in MONAILabel.

We can't use the search API in NGC API doc to find all models. May need the NGC team to add support for this one.
