WIP: Attempt to speed up CI

[chaptersix]

Description
This PR aims at reducing the execution time of the setup-with-retry Github action.
Resolve: #30706

• This action is a wrapper that loads form the cache, add 2 retry steps for any other action that uses the action, and runs env.BUILD if defined.
• The slowness of the builds when cached appears to be due to
  • Pulling from the container image cache
  • the install of the uv package manager causing a cache miss
• Existing Image is ~ 3.8GB with the largest layer being 1.5 GB

Solution :

1. Removing dependencies
2. creating more layers
3. update image tag have pr-123 was triggered by a PR?

Verification

1. All tests pass without modification
2. After this PR merges and the new openpilot_base image is published, build times fall.
