Notes about the bof

* Can we put our stuff on https://devdocs.io/ ? we can try 
* api.k.o and dev.k.o will stay separate with cross-references in the short term
* Move stuff from community and techbase to [https://develop.kde.org develop.kde.org]
* Don't blindly move everything, dev.k.o should only have high-quality content
* For QML documentation, in the short term move doxyqml to KDE infra and see if we can fix some of the major issues. Longer-term sees if something appears that we may be able to use, maybe based on the Qt 6 QML parser lib.
