net/cloud-init-devel: Bump to latest main after 24.1 release

please note that due to an error in the release process, there's no 24.1
tag on main, that's why the version number is still based on 23.4

Same workaround as net/cloud-init for python.mk autoplist bug described
in https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=205056.
