- Rename the workflow
- Fix an error message
- Fix unused variable
- docker-compose.yml -> docker-compose.yaml
- Remove obsolete `version` attribute from docker-compose.yaml
- Refactor case statement in run-test.sh
- Remove unnecessary test assertions. The test doesn't need to check
  that all expected binaries are in a teleport package.
