Python upstream ended 3.5 support a year ago:
https://devguide.python.org/devcycle/#end-of-life-branches

Currently supported branches are listed at:

That's an upstream limitation:
https://github.com/nmap/nmap/issues/1176
https://github.com/nmap/nmap/pulls?q=is%3Apr+python3+is%3Aopen

PyGObject 3.x definitely supports Python 3 - we ship that in Solaris:
https://github.com/oracle/solaris-userland/tree/master/components/gnome/pygobject3

Pygtk2 does not - it's limited to the deprecated gtk2 and obsolete Python 2,
and as you discovered, the replacement path for it is PyGObject.

Not everything has finished porting from GTK+2 to GTK+3 yet, and now
the GTK maintainers have released GTK+4 and moved GTK+3 to the deprecated
(but not yet totally unsupported) list alongside GTK+2.
