Changelog Entry

Description

• This PR will reduce the docker image size by ~1.2GB. This reduction is the result of squashing multiple RUN instructions into one and uninstalling build dependencies (uv git build-essential gcc python3-dev). It will also bump the frontend alpine base image to 3.22 (3.20 is end of life in ~6 months)

Changed

• Reduced docker image size

Additional Information

• In a Dockerfile, each RUN creates a new layer. Layers are immutable, and all files created in one layer are carried into the next, even if they are deleted later.
• If the build dependencies are necessary during runtime then a smaller reduction in size can still be achieved by only joining the multiple RUN instructions.
