checkpoints for run_sample_video.sh

Hi, thank you for sharing the work!

I need T2V model so tried using checkpoints here https://huggingface.co/LargeWorldModel/LWM-Text-1M-Jax/tree/main with run_sample_video.sh.

But it seems the vqgan checkpoint is missing. Should I use a vqgan checkpoint of another model such as LVM-Chat-1M-Jax?
