fix: webhook and 4 other nodes incorrectly marked as non-triggers

Updated trigger detection logic in both parsers to check if a node's group array includes 'trigger'. This fixes an issue where webhook, cron, interval, and emailReadImap nodes were not being identified as triggers despite having category='trigger'.

Note: After pulling this change, run `npm run rebuild` to update your local database.

Fixes #13
