Build command always return code 0 despite failing in linux

System information

github actions server, ubuntu image

Issue description

I noticed that despite the build failing, this command:

$GODOT_EXECUTABLE --export-release --headless ${build} || die "Failed to create ${build} build"

The command die never executes, which means the engine is returning code 0, which means success, and that's not what it should happen.

Steps to reproduce

1. Create a project that should fail on build
2. Execute a command, let's say `$GODOT_EXECUTABLE --export-release --headless "Android"
3. Then execute echo $? to display the error code, it will always be 0

Minimal reproduction project

N/A
