fix(tests): repair two install lines #1076 spliced mid-line

[svc-template-updater]

#1076 inserted a dep install into 20 tests.sh. In two of them the insertion landed mid-line and split the original runner install in half, leaving papermill <package-spec> as a command of its own:

# asynchronous_inference
uv pip install --system --no-cache-dir uv pip install -r python_depset.lock ...
papermill "nbconvert==7.16.6" ipykernel
# workspace-intro
pip install -q uv pip install -q --system emoji
papermill nbconvert==7.16.6 ipykernel

Both are valid bash, which is why that PR's bash -n sweep came back clean. Neither installs papermill, and the orphaned line runs it with a version pin as its input notebook.

Impact

template-probe 146 — the first daily run after #1076 merged — failed on no such option: --system, the only red job of 38. asynchronous_inference isn't in the probe set, so its breakage was silent.

The check-depsets pre-commit hook passed on both: it greps for the lock path, so the mangled line still looked like an install.

Testing

/test-template asynchronous_inference workspace-intro.
