fix: update ChainLightningSceptreInteraction to handle only secondary interactions and adjust Chain_Hit_Effect duration

- Added a check in ChainLightningSceptreInteraction to return early if the interaction type is not Secondary.
- Reduced the duration of Chain_Hit_Effect from 0.6 to 0.05 for improved gameplay balance.
- Removed the primary interaction from chain_lightning_sceptre.json to streamline item functionality.

Tests: All tests passing. Build: ./gradlew clean build successful.
