Add empty folder "public/data" to the repo
Created by: daniloisr
When installing the project I noticed that we need to manually create the public/data folder, but this can be skipped if we add it to the repo using the common pattern of adding an empty file called .gitkeep inside it.
This is a minor improvement but can save someone that forget to manually create the folder when doing the project setup
- All BrainBox tools behave as expected
- These changes do not require tests because it don't touch in the source code
