Update outdated refs to the prebuilt-jobs.md file (#698)

Updates lingering refs to the old `prebuilt-jobs.md` file. These refs
now point to the new `prebuilt-anomaly-detection-jobs.md` file that was
added in #695.

Previews:
- [Anomaly
detection](https://docs-v3-preview.elastic.dev/elastic/docs-content/pull/698/solutions/security/advanced-entity-analytics/anomaly-detection)

 Machine learning jobs look back and analyze two weeks of historical data prior to the time they are enabled. After jobs are enabled, they continuously analyze incoming data. When jobs are stopped and restarted within the two-week time frame, previously analyzed data is not processed again.
