[Bug]: CI Workflow fails due to pyink version mismatch between setup.sh and GitHub Actions

[Perseus14]

Describe the bug

Currently, there is a version mismatch for pyink between the local developer setup and the GitHub Actions workflow (CPUTests.yml).

The setup.sh script installs the latest version of pyink (currently 25.12.0), while the GitHub workflow strictly enforces pyink==23.10.0. As a result, when developers format their code locally using the setup script's version, the CI/CD pipeline fails during the formatting check because it evaluates the code against the older version.

To Reproduce

Steps to reproduce the behavior:

• Run bash setup.sh MODE=stable DEVICE=tpu locally (installs pyink>=25.12.0).
• Format the codebase locally using the installed pyink.
• Push the changes to a PR.

The GitHub workflow fails on the formatting check because it expects formatting from pyink==23.10.0.

Expected behavior

The version of pyink used locally should perfectly match the version enforced by the CI pipeline to prevent unnecessary build failures and contributor friction.
