Request to Upgrade SageMaker Base Image to Use mambaorg/micromamba:ubuntu22.04

[ChaonengQuan]

🚀 The feature, motivation and pitch

Motivation

The mambaorg/micromamba:jammy image is no longer receiving new releases, as confirmed by the open-source maintainers. This means it is effectively deprecated and stuck at micromamba version 1.5.10.
Source: mamba-org/micromamba-docker#573 (comment)

Proposed Solution

Switch to using the mambaorg/micromamba:ubuntu22.04 image. This image is equivalent to jammy but continues to receive updates and includes micromamba version 2.0.5.

Impact

• Ensures the SageMaker base images stay aligned with a maintained upstream image.
• Avoids potential security vulnerabilities (CVEs) that may arise from using an unsupported image.
• Leverages the latest improvements and bug fixes in micromamba 2.x.
