Remove redundant apk update calls in Dockerfile

[PeterDaveHello]

Description

Remove redundant apk update calls in Dockerfile. The apk upgrade commands already utilize the --no-cache option, making the separate update step superfluous and ensuring the latest packages are used without maintaining a local cache.

Motivation

An additional apk update in Docker image layers increases the image size with no benefits since apk upgrade --no-cache already fetches the latest package information.

2. Consider using a specific Alpine version tag for better reproducibility

This PR looks good overall. It correctly adds explicit apk upgrade --no-cache commands in both build stages of the Dockerfile. I have one minor suggestion to improve the documentation.
