Add "new" models to ONNX Model Hub tool

What is the problem that this feature solves?

Automatization of downloading recently added models via onnx.hub python tool.

Describe the feature

Currently, the Hub can work only with legacy models according to https://github.com/onnx/models/blob/main/ONNX_HUB_MANIFEST.json. The legacy models are going to be removed, unlike ONNX Hub tool. At least I haven't seen any deprecation note

Relevant Model Zoo feature areas

• ONNX_HUB_MANIFEST
• ONNX Model Hub

Notes

As I understand a new manifest can be generated easily https://github.com/onnx/onnx/blob/main/docs/Hub.md#contributing-an-official-model

Hi @Maxim-Doronin
Thanks for the issue. The HUB has not been updated with the new models yet.
And, if the legacy models are being used extensively we can continue to maintain them in the zoo under archive.
If you are interested in contributing an enhancement to the HUB, please feel free to do so. Contributions are greatly appreciated, and we're more than happy to provide guidance or assistance if needed.
