fix(renovate): anchor managed version values to digit-start

Require managed version values to start with a digit in both Dockerfile ARG and compose matchStrings. Kills the false-positive class where any *_version key with a non-version scalar (e.g. latest, stable) becomes a pypi lookup. Verified no-op on the current corpus: identical 26-capture set before/after.
