docs(aclv2): fix broken links to and from the new ACLv2 page (#9796)

docs(aclv2): fix broken links

The ACLv2 page was created and merged at roughly the same time we split the documentation pages into two sections (XO6 and XO5), so the change in file structure broke some links to and from that ACLv2 page.

This commit fixes the links so that the Docusaurus build can complete without errors.

 A selector is evaluated against each object's properties. If it matches, the privilege applies; otherwise it does not.
