Adjust ES link builder to build links in our format

[shainaraskas]

To keep links from ES live, we need to update the link builder from 9.0 forward to use our new link format

VERSION_COMPONENT needs to stay in some form to future-proof the system. See discussion

Docs links also need to be refreshed to point to the equivalent doc in the new system. This could be undertaken by a writer when we understand the link format required
