out of curiosity, why is the 8.3 external modules folder different in docs vs .ignition-jvm-args?

my compose command:

```python
    command: >
      --
      -Dignition.projects.scanFrequency=5

```

but found in .ignition-jvm-args.\<8 random chars\>:  
`-Dignition.gateway.externalModulesFolder=data/var/ignition/modl`

[docs](https://www.docs.inductiveautomation.com/docs/8.3/appendix/reference-pages/gateway-configuration-file-reference/gateway-and-gateway-network-parameters#docker-image-external-modules-folder):
