Yes definitely, many lines of shell in YAML (or Docker files) is one of my pet peeves. It's always better to invoke a shell script. Then you can use ShellCheck on it, your editor will syntax highlight it, you can parse it with Oil (osh -n) [1], etc. And yes there shouldn't be too much of a difference between what developers do locally and what the CI does. It's sort of an anti-pattern if you have a bunch of automation that can only the CI can run. The developer should be able to run it on their machine too, without CI, and without YAML ...
