docs: make a more logical doc structure for xo6 (#9972)

This commit creates a new, refreshed tree structure
for the XO 6 documentation, which we intend
to be more helpful for readers and XO 6 users.
New sections are created, to be completed later.
Additionnally, the ACLv2/RBAC page has been
moved from the Support section to the Security section.
