Provide a complete runnable pre-training demo.

[forceworker]

he pre-training process provided in the current scGPT-integrate-huggingface-model branch cannot run due to missing necessary files. It is unclear how the data is processed and organized. I would like to create a runnable pre-training demo to help better understand how scGPT works.

Can you do a success run after pip install or poetry install, I can not even run the tutorial program after installation referring to the installation guide.
