The changes in the .circleci/config.yml file of the ethereum-optimism/supersim repository include:

Switching from using a machine executor with ubuntu-2004 to a docker executor with the image us-docker.pkg.dev/oplabs-tools-artifacts/images/ci-builder:v0.35.0.
Removing the install-just command and its associated steps.
Removing the install-just step from several jobs.
These changes indicate a shift from using a machine-based executor to a Docker-based executor and the removal of the just tool installation and usage in the CI process.
