[Bug]: Colab + Cloudflared - it works, but slow and console is red

### Frontend Version

1.18.9

### Expected Behavior

Loads faster and doesn't have console errors.

### Actual Behavior

After cloudflared tunnel started, it still takes 2+ minutes before UI appears in the browser tab and console is full of errors:

### Steps to Reproduce

I used the cloudflared example from ComfyUI notebook examples.

********** ERROR ***********

comfyui-workflow-templates is not installed.

Please install the updated requirements.txt file by running:
/content/venv/bin/python -m pip install -r /content/ComfyUI/requirements.txt

This error is happening because the ComfyUI frontend is no longer shipped as part of the main repo but as a pip package instead.

If you are on the portable package you can run: update\update_comfyui.bat to solve this problem
