Summary
The full and slim docker images for SF CLI only contain sfdx-scanner (which is v4.x, and now retired), rather than code-analyzer (v5.x) which has been around for several months now and is the plugin everyone should be using.
This means an extra 20-25s of plugin installation is required on top of bringing down the docker image when used in CI pipelines
Steps To Reproduce
https://hub.docker.com/r/salesforce/cli/tags
No docker images contain the code analyzer plugin https://www.npmjs.com/package/@salesforce/plugin-code-analyzer
Expected result
We would expect code-analyzer plugin @latest to be installed
Actual result
Only sfdx-scanner is installed which is now retired
