Simplify and unify apk usage in Dockerfiles (#3407)

Browse Source 
Replace `apk update` and `--update` flags with `--no-cache` across
Dockerfiles to improve consistency and eliminate unnecessary cache files.

This change reduces image size and ensures up-to-date package indices
without leaving temporary data. It also aligns with best practices
recommended for Alpine-based Docker images.
