Open a notebook without cloning locally the repository

This is a question / feature request about if it would be interesting to provide an option such that one could open a notebook from github on JupyterHub without cloning the github repository. Similar to what can be done with Google Colab. For example:
- Jupyter notebook on GH: https://github.com/pytorch-ignite/nbs/blob/main/nbs/00045260-2b6e-4057-8fa6-f26f992e5cd5/ignite-template-text-classification.ipynb
- URL to open with colab: https://colab.research.google.com/github/pytorch-ignite/nbs/blob/main/nbs/00045260-2b6e-4[…]6-f26f992e5cd5/ignite-template-text-classification.ipynb

In this case user would open the notebook from a temporary folder and can optionally save it into their working folder.

Please, let me know if this feature could be interesting and possible to implement. Thanks!
