fix: update cron field schema description and fix formatting

- Updated the cron field description in provider/script.go to include detailed 6-field format explanation
- Fixed formatting issues in documentation (removed extra spaces before comments)
- Regenerated documentation to ensure consistency between schema and docs
- This ensures the documentation generation preserves the detailed cron description instead of reverting to generic text
