Removes the redundant import re statement from Step 2 of the text-to-video pipeline tutorial. The re module was already imported in Step 1's code block, making this duplicate unnecessary and potentially confusing for readers following the tutorial.

Agent Response

I've fixed the broken import in the text-to-video pipeline tutorial.

Issue found: In Step 2, there was a duplicate import re statement at the start of the code block. The re module was already imported in Step 1 along with requests, time, and os, making this second import unnecessary and potentially confusing for readers following along.

I also verified that all the model links in the tutorial are working correctly (Qwen3 32B, Flux Schnell, Flux Dev, and WAN 2.5 all exist).
