Fix broken ml job links and remove duplicate prebuilt jobs page (#850)

* Removes duplicate
[reference/security/prebuilt-anomaly-detection-jobs](https://docs-v3-preview.elastic.dev/elastic/docs-content/tree/main/reference/security/prebuilt-anomaly-detection-jobs)
page and keeps
[reference/data-analysis/machine-learning/ootb-ml-jobs-siem](https://docs-v3-preview.elastic.dev/elastic/docs-content/tree/main/reference/data-analysis/machine-learning/ootb-ml-jobs-siem).
* Contributes to #755 by
fixing broken prebuilt job links in `ootb-ml-jobs-siem`.
