godot cli does not set non zero exit code on error

[AlexanderLangguth]

Godot version

Godot Engine v4.2.rc1.mono.official.ad72de508 and any other, including v3.x

System information

Windows, Linux

Issue description

I have been building godot a lot now using gitlab pipelines and regardless of which godot version, whenever any error happened during the build or export the cli always exited with exit code 0, resulting in succeeding pipelines, although the build step should have failed.

Could you please make the CLI commands (at least the build and export ones) compliant with regular build CLIs that actually set the exit code to anything != 0, so that automated build pipelines actually fail when the build was not successful?

I don't know how this was never reported. I guess Godot was not used in any major production system yet and everyone always just exported by hand.

Steps to reproduce

Have any error in your godot project that fails the build or export command.
As a simple example I just export something that is not configured, which leads to red error messages, but also exit code 0.
Example: godot . --export-debug "test" "./out" --headless

Minimal reproduction project

It's just a completely empty Godot project. In this case based on Godot version 4.2-rc1, but any version I tested so far, including 3.x had this issue.
