Auto merge of #14577 - epage:tests-basic, r=weihanglo

test: Migrate remaining with_stdout/with_stderr calls

### What does this PR try to resolve?

This is part of #14039 and is another step towards us not needing our own redaction logic.

Along the way, I switched us to using `expect` to make it easier to tell when `allow(deprecated)` should be removed.

### How should we test and review this PR?
