ATR-22283: add missing TStreamerInfos for Trigger classes in BS
- When checking for new TStreamerInfos with dictwrite.py, include trigger classes by default
- Update bs-streamerinfos.root to include TStreamerInfos for all classes mentioned in TriggerEDMRun3.py, for collections that are serialized to bytestream. This fixes the new nightly test (jira in the MR title)
- Small update of the function to categorize trigger containers
