Build.yaml (build tutorials for docker) action workflow has ~15 deprecation warnings

## Actual Behavior

Looking at any run of the Build Actions workflow you see ~ 15 warnings indicating we're using old out of support github actions, and/or github features. Examples are old checkout actions, and also using save state instead of .env files (which we already use in this repo today under /.github.

We should PR a fix to bring these to 0, and take a pass for any other old unsupported actions or stacks in use. This will also help stability and security of the supply chain.

## Steps to Reproduce the Problem
