   PR summary

   This PR updates the mcr.microsoft.com/devcontainers/universal:2 image to base:ubuntu image. It also makes following changes to ensure container is light, flexible and supports setup.sh installation :

   • Changes strict requirement of 4-cores setup to flexible option for 2-cores or 4-cores setup.

   • Adds SSH feature.

   • Adds Conda ( since base:ubuntu doesn't readily comes with Conda ).

   • Updates conda environment path for base:ubuntu.

   • Explicitly invokes bash for onCreateCommand to avoid permission related issues.

   This only consumes 8 GB space. I have tested this and it works fine.

   

   Fixes #32374

   Was dropping hostRequirements entirely intentional or should cpus/memory be explicitly (e.g cpus: 2) so Codespaces doesnt default to an unpredictable size for a build this heavy?

   @Maharshi-Paul it was intentional, because that lets you choose between 2-cores cpu and 4-cores cpu. ( When creating it by selecting New with Options ).

   And when you create directly without setting any options, Codespace defaults to 2-cores cpu in this case. However, explicitly defining it to be 2-core cpu will not let you choose 4-core cpu for heavy work and vice-versa. Hence dropping it was the flexible option.
