Use "c" instead of "s" in sed to handle branch names with slashes

[Peter-Sh]

c would just replace whole string with literals folowing the command without involving regexp

Note

Low Risk
Small build-script change limited to Docker image module version patching; low blast radius aside from potential build-time differences if Makefile formatting varies.

Overview
Updates the Alpine and Debian Dockerfile.j2 templates to change how Redis module versions are injected during custom_build.

The sed commands that set MODULE_VERSION in module Makefiles now use the line-replace (c) form instead of a regex substitution, avoiding failures when version strings contain characters like / (e.g., branch names).
