[DOCS] Fix broken links

[lcawl]

Relates to elastic/docs#2743

There are hard-coded links that seem to be using an inappropriate format and result in errors like this:

16:35:51 INFO:build_docs: /tmp/docsbuild/target_repo/html/en/security/8.10/threat-intel-windows-registry-indicator-match.html contains broken links to:

To get the V8.10 documentation working, I am converting these all to internal links (<<id,label>>) however if these are generated files the scripts that generate them will need to be fixed too.
