[demo] Automate doctr demo update via CI job

[felixdittrich92]

This PR:

• Add required files to auto update the hf demo via CI
• Add corresponding CI job - allow also manual action trigger for testing or manual refresh

Any feedback is welcome 🤗

@odulcy-mindee HF_TOKEN needs to be added as secret :)

To much overhead with the cron job ? 😅

I added the token. Hopefully, it should have enough rights to update the space. Thank you for automating that.
