Fix ARM-TTK validation: update API versions, remove disallowed parser and backup dir

- Update savedSearches apiVersion from 2022-10-01 to 2025-02-01 in mainTemplate.json
- Remove Parsers/LookoutEvents_ARM.json (only .yaml/.md allowed in Parsers)
- Remove Package/3.0.1/ backup directory that caused redundant ARM-TTK scan failures
- Rebuild 3.0.2.zip with corrected mainTemplate.json
