Use ValueSource to run pod commands for CocoaPods publishing

[KevinSchildhorn]

Issue: #267

Summary

Moving pod calls to use a ValueSource.

Fix

• Using a ValueSource instead
• If there's an exitValue error, we catch it and then throw the underlying error
• Some formatting

Testing

• ./gradlew test
• ./gradlew build
• manual testing

Not sure ValueSource is needed, but it's working and I don't mind a little more structure
