CI/FIX: Update container deploy GitHub Actions

Change Summary

Overview

I tested it locally and it looks like it shrinks the line as expected now.

instruments="ultra"; echo "$instruments" | tr ',' '\n' | tr -d ' ' | grep -v '^$' | jq -R -s -c 'split("\n") | map(select(length > 0))'

outputs:

["ultra"]

There was also a failing summary step that I had Claude update as well.
