refactor(trigger): enhance update method to use explicit None checks

- Updated the `update` method in `SubscriptionBuilderUpdater` to use 'is not None' checks instead of truthy evaluations for better handling of empty values.
- This change improves clarity and ensures that empty dictionaries or strings are correctly processed during updates.
