Update architecture adoc so that its batch-asciidoc variable is set

* Updated all docs that had `batch-asciidoc` declared to use attributes.adoc instead.
This way we can set the variable in one location and all adocs can take advantage of it.
* Also made sure that `batch-asciidoc` was set to use a relative path vs. the link in the UI.
This is because the PDF can't use a URL that contains the `-` character.

Resolves #4268
