Remove redundant apk update calls in Dockerfile

Removed unnecessary `apk update` commands in Dockerfile. 
The apk add commands already utilize the `--no-cache` option, making the update step superfluous and ensuring the latest packages are used without maintaining a local cache. An additional `apk update` in another Docker image layer will increase the image size with no benefits.
