Regenerate lockfiles: harmonise setuptools 78.1.1 across llmcompressor runtimes

[coderabbitai]

The workflow run https://github.com/jiridanek/notebooks/actions/runs/16814498242/job/47627775646 was expected to refresh Pipfile.lock / requirements.txt files, but two llmcompressor images still pin setuptools==75.8.2:

• jupyter/pytorch+llmcompressor/ubi9-python-3.11/requirements.txt
• runtimes/pytorch+llmcompressor/ubi9-python-3.11/requirements.txt

This leads to a dependency conflict with the rest of the repository, which now uses setuptools==78.1.1.

Acceptance criteria

1. Regenerate the lock-files for both images so that setuptools>=78.1.1.
2. Verify CI passes on all architectures after regeneration.
