Option parsing failed: Unknown option --appimage-version

I cloned the repo and ran `ARCH=x86_64 ci/build.sh`. It fails with
```
+ /tmp/appimage-test-0oPFX/appimagetool-x86_64.AppImage --version
appimagetool, continuous build (commit 672b3d0), build built on 2022-04-02 11:42:47 UTC
+ /tmp/appimage-test-0oPFX/appimagetool-x86_64.AppImage --appimage-version
Option parsing failed: Unknown option --appimage-version
+ error
+ echo 'Error: command failed'
Error: command failed
```

Interestingly this does not happen on the CI builds (e.g. the [latest](https://github.com/AppImage/AppImageKit/runs/5394769126?check_suite_focus=true))... Any hint what I'm doing wrong?
