#### 🎯 Subject of the issue

Experienced behavior:
<!-- Describe issue here -->
Docker container nerdfonts/patcher errors out when run. I've attempted both compose and run syntax:
```yaml
 services:
   nerdfonts-patcher:
    command: |
      --mono
      --adjust-line-height
      --progressbars
      --complete
    container_name: nerdfonts-patcher
    image: nerdfonts/patcher
    #user: ${UID}:${GID}
    volumes:
    - ./nf-in:/in
    - ./nf-out:/out
```
or `docker compose run --rm -v ./nf-in:/in -v ./nf-out/out nerdfonts/patcher --mono --adjust-line-height --progressbars --complete`.

Both result in:
```shell
Running with options:
 --mono --adjust-line-height --progressbars --complete
Parallelism 0
fontforge -script /nerd/font-patcher -out /out --mono --adjust-line-height --progressbars --complete /in/berkeley-mono/OTF/BerkeleyMono-BoldItalic.otf
