Docker performance improvements and reduce image size (#1016)

* refactor(makefile): ♻️ remove repetitive command

* chore(Dockerfile): Refactor Dockerfile to use multi-stage build
- Change base image from python:3.11-slim to python:3.11-alpine in the builder stage
- Use apk package manager instead of apt-get to install dependencies
- Remove unnecessary sudo command
- Use pip install --no-cache-dir instead of pip install
- Add second stage in Dockerfile for final image
- Copy dependencies and entrypoint script from builder stage to final stage

* chore(entrypoint.sh): update shebang to use `/usr/bin/env sh`
- add coding utf-8 declaration
- use `find` command to patch permissions of generated files
