test(health): assert SERVICE_VERSION matches the Helm chart version

Catches drift between the Python package version (what /health reports
to clients) and the chart version (what's actually deployed). If they
get out of sync, a client gating on /health's version may try to use
features that aren't actually shipped.

Reads kubernetes/code-interpreter/Chart.yaml directly via a small regex
so the test has no extra dependencies.
