[jzheaux]

The following shows documentation that is currently missing on main:

?> git diff --diff-filter=D --summary 5.5.x:docs/manual/src/docs/asciidoc/_includes/servlet/integrations main:docs/modules/ROOT/pages/servlet/integrations/

 delete mode 100644 concurrency.adoc
 delete mode 100644 data.adoc
 delete mode 100644 jackson.adoc
 delete mode 100644 localization.adoc

They should be ported over.
