are we using Antora? I found this merged PR
<https://github.com/apache/fineract/pull/5391> setting up new asciidoc per
FINERACT-1956 <https://issues.apache.org/jira/browse/FINERACT-1956>, but
the work seems to be abandoned and I can't find anywhere we're actually
using Antora. I think I want to clean this up and cancel FINERACT-1959
<https://issues.apache.org/jira/browse/FINERACT-1959> so we don't end up
with wasted effort like this
<https://github.com/apache/fineract/blob/5a93304677061501f5d0c243b8dbf84752e08b0b/fineract-doc/modules/ROOT/pages/oidc-federation.adoc>
(it looks like the oidc federation docs are in the wrong place and aren't
published/viewable with the rest of the asciidoc)
