CI does not fail on multiline script errors

[sunjay]

We have a few multiline scripts in our Azure DevOps Pipeline. For example:

https://github.com/sunjay/turtle/blob/dc80b658717134366b7fc387ce251f327580d1bb/azure-pipelines.yml#L61-L66

Originally when I set this up, I expected that if any of those lines failed, the whole step would fail, but apparently that is not the case.

This means that it is theoretically possible for our CI to let through build errors, test failures, or worse. Any help fixing this would be appreciated. This is a terrible default, but we'll just need to work around it however we can.

Note that it isn't enough to just add set -e at the top of the script since that won't work on Windows.
