Update env Templates

[coreyphillips]

• Not sure if there's a better way to handle this?

Type of change

• Bug fix (non-breaking change which fixes an issue)

Tests

• No test

QA Notes

• We should now be able to run the following command without an error resembling the attached screenshot.

git clone [email protected]:synonymdev/bitkit.git && cd bitkit && git checkout update-env-templates && yarn install && cd ios && pod install && cd ../ && yarn ios

react-native-dotenv has an option to allowUndefined

bitkit/babel.config.js

Lines 12 to 17 in 08c7a8c

	'module:react-native-dotenv',
	{
	safe: true,
	allowUndefined: false,
	},
	],

Not sure if that would be the better solution because we actually want the app to throw the above error for most env vars. I think I prefer the empty string.
