Indent the JSON file with appsmith UI

[bkowshik]

NOTE: This PR should be merged to main only after merging #109 and deleting the branch.

---

The purpose is to make diff on git / Github possible for the appsmith .json file. Currently, all of the app is just one line.

Ex: https://github.com/datakind/Data-Observation-Toolkit/pull/109/files

Not sure about what all needs to be considered before making this change though. Below is the size comparison and it looks OK to me given the advantages we get with git-diff.

# Since of the file before indentation.

# Size of the file after indentation.
$ ls -lh docker/appsmith/DOT\ App\ V2.json

Completed the appsmith tutorial and the folder structure isn't one large .json file. Instead, the structure of the application is very clear from the folder structure and additional resources like queries / ui are also in the same folder. Don't know yet on how to move to such a setup, but I think having a structured folder would help make the codebase even more accessible to new contributors.

NOTE: Import from Git repository is in now Beta. 👏

Because of the indentation, PR reviews are significantly easier now. This is one commit where the query is modified and it's easy to see the diff because of the indented .json file of appsmith UI.

Update

In addition, wrote the Appsmith code into this repository for reference: https://github.com/bkowshik/dot-ui It's significantly to view the pages, queries, etc in this structure instead of a giant .json file. 😅
