Previous commit's regex substitution dropped `COPY requirements.txt .`
and the initial `RUN pip install --no-cache-dir -r requirements.txt`
because of a bash-heredoc escape interaction (the \1 backref was
consumed before the python regex saw it, leaving a SOH char). This
restores both lines with the conditional version-pin upgrade after.

Closes the cache trap structurally for this template — same fix
already shipped in claude-code + hermes. publish-image.yml caller
forwards client_payload.runtime_version (set by cascade) to the
molecule-ci reusable workflow as runtime_version input. Reusable
workflow forwards it to docker build as a --build-arg. Dockerfile
declares ARG RUNTIME_VERSION before the pip install layer so cache
key is sensitive to the version. The pip install RUN does an extra
targeted upgrade to guarantee the exact version when ARG is set.
Pairs with molecule-ci PR #12 + molecule-core PR #2181.
