DO NOT build the initial image on 'development' branch

[Jiayuli-CU]

If you build the backend Docker image for the first time, or rebuild it from the very beginning for certain reasons, do it on the main branch! Yesterday my docker desktop crashed for strange error so I had to reinstall it with all my images and containers lost. After I re-built the backend image on development branch and ran the shell script to create mock data, error message showed up saying "Insufficient Permissions" as defined in our utils package. I tried to remove the user authentication, but it still didn't work. It took me a whole day to debug the problem before finally gave up and re-built on the main branch, and everything worked perfectly again.
