[FEATURE] Add dependencies to support dev mode on HF Spaces

[jfcalvo]

Hugging Face recently added support for dev mode. Enabling some features like connecting to the space through SSH or enabling a VS Code server so remote changes can be done easily.

Right now dev mode can't be enabled on Argilla because some dependencies are missing. We should modify our Argilla template to add these dependencies.

More information about the new dev mode can be found here: https://huggingface.co/dev-mode-explorers
