docs(kubernetes-events): add missing parameters and fix defaults

- Add missing config parameters: db.journal_mode, db.locking,
  dns_retries, dns_wait_time
- Fix tls.verify default from 'On' to 'true' to match source
- Fix kube_namespace default from 'all' to none
- Sort parameters alphabetically
- Align table format with other input plugin docs
- Expand tls.debug description with all debug levels

Fixes #2272.
