drgndoc: handle removal of deprecated ast nodes in Python 3.14

The Num, Str, Bytes, Ellipsis, and NameConstant ast nodes have been
deprecated since Python 3.8 and were finally removed in Python 3.14.
This causes an AttributeError in drgndoc. We already transform them to
the replacement Constant node, so we just need to stop trying to use the
old names.

Fixes https://bugzilla.redhat.com/show_bug.cgi?id=2325185.
