Note

Upgrade Alpine base image in keto Dockerfile from 3.7 to 3.23.4

Updates Dockerfile-alpine to use alpine:3.23.4 as the runtime base, replacing the end-of-life alpine:3.7. This brings in updated OS libraries and security patches. Risk: the newer Alpine version may include different system library versions that could affect runtime behavior.
