Update docker-entrypoint.sh - Load ENVs from file

This commit allows the end user to upload a .env file from the "Interactive Terminal" tab under the Volume Browser section. 

The user would then use the upload button to upload their .env file.

Finally, the user would go to global component control and restart the app to have it pickup the file.
