Description

Currently, there are multiple Dockerfiles maintained for VSCode devcontainers within the project. This setup leads to redundancy and potential inconsistencies across development environments.

Possible approaches

• Design a single, unified Dockerfile that accommodates the needs of various development scenarios without compromising functionality.
