Add new DataDoc frontend - #48055

@TurnerRiley and I paired on this PR, which finishes functionality to add a new Data Doc.

This work is part of https://codedotorg.atlassian.net/browse/PLAT-1279 –– Curriculum Writers can add new Data Docs.

To see functionality, go to http://localhost-studio.code.org:3000/data_docs/new. It should make you add Levelbuilder permissions to your local account before you can view the page, and you should be able to put in some basic stuff. What actually happens after you submit will come in a separate PR (see follow-up work).

Deployment strategy

Follow-up work

• Create page to actually see the DataDoc that was created –– this is a separate work item in the engineering plan. We should redirect to the corresponding page once a data doc is created.
• Add UI test once we have the show page working.
