Detect secrets hook is missing in Dev Container

[kimsey0]

When running the ci.sh script from a clean Dev Container, I get the following message at the end of the execution:

./ci.sh: line 30: detect-secrets-hook: command not found

This looks to me like detect-secrets isn't being installed properly in the Dev Container. There doesn't seem to be any references to it in the Dockerfile. Should the Dockerfile run setup_ci.sh (or the relevant lines from it) to install detect-secrets?
