Subject: [PATCH] [vscode][3/n] Setup Env Variables: Use env template file for
 new files

If the file does not exist, created a template file with some helper text to help guide people on how to set their environment variables.

Next PR I will handle the use case for when the env file already exists

## Test Plan
