 As before, environment variables with names that start with `DHIS2_` are added to the app, and can be picked up from `.env` files or on the command line for example. Before, the platform had to add `REACT_APP_` before `DHIS2_` so that Create React App would add the variable to the app, so a variable like `DHIS2_MY_VAR` in the environment would become accessible on `process.env.REACT_APP_DHIS2_MY_VAR` in the app. Now, the `REACT_APP_` prefix isn't needed, so the variable can be accessed on just `process.env.DHIS2_MY_VAR`.
