chore: set dir to auto for new apps [LIBS-645]

[tomzemp]

See https://dhis2.atlassian.net/jira/software/c/projects/LIBS/issues/LIBS-645

This PR updates the configuration for newly initialized app to set dir: 'auto' so that by default apps will follow direction of user language, and hence display 'rtl' for Arabic, Urdu, etc.,

(After this is merged, https://github.com/dhis2/cli dependencies need to be updated)

This would have breaking side effects for existing apps unfortunately, since this file is doing double-duty as the boilerplate file that's copied into new apps and as defaults that are read from here then applied to existing apps' config...

In the Vite for plugins branch though, I have some work to decouple the boilerplate and the config defaults (since applying an app entrypoint to an 'app' with only a plugin entrypoint makes things complicated) -- maybe we could point this one at alpha once that one is merged?

🤦‍♂️ Thanks.

Sounds good to address later if the vite changes will make this easier. I'm going to close for now 🙏
