Python Workers template E2E tests fail because workers-py 1.17.9 now requires uv >=0.13.4, while CI installs uv 0.12.3. The dev server exits with a version error and the tests eventually report fetch failed.

Bump the shared CI uv pin to 0.13.4 to meet the new requirement.

• Failing CI job: https://github.com/cloudflare/workers-sdk/actions/runs/39909778553/job/120332197210
• Upstream requirement change: fix(cli): force uv>=0.13.4 with eMudhra vuln fix workers-py#293

Validation:

• Reproduced hello-world:python failing with uv 0.12.3 on main.
• With uv 0.13.4, ran pnpm --filter create-cloudflare test:e2e workers -t :python (all four Python templates passed on the first attempt; 17 unrelated cases skipped).
• pnpm check:workflows
• pnpm exec oxfmt --check .github/actions/install-python-uv/action.yml
• git diff --check

  • Tests included/updated
  • Automated tests not possible - manual testing has been completed as follows:
  • Additional testing not necessary because: this only updates CI tooling; the existing Python-template E2E tests cover the failure and were run locally.
• Public documentation
  • Cloudflare docs PR(s):
  • Documentation not necessary because: this only changes the uv version installed in CI.
