Additional context:
This might be considered as a design change as it's not returning non Zero code, instead it's returning Zero code even when there was build failed.

Start at the entry point for `func azure functionapp publish` and trace how remote build status is retrieved and converted into the command's exit code. Reproduce the command with a failing remote build, then verify that the publish command returns a non-zero exit code when the build fails.
