Fix CI: Replace Microsoft universal image with custom implementation

The Microsoft devcontainers/universal:linux image was failing with Maven
download 404 errors. This replaces it with a custom implementation based
on the stable devcontainers/base:ubuntu image and manually installs the
universal development tools including:

- Common development tools (build-essential, git, etc.)
- Programming languages (Python, Node.js, Java, Go)
- Build tools (Maven)
- Utilities (jq, htop, tree)

This should resolve the CI failures while providing equivalent functionality.
