Propose release version 0.9.0

hello cluster api kubemark provider community,

i would like to propose making a 0.9.0 release which is primarily an update to cluster-api version 1.9 and kubernetes version 1.31.

i realize that we skipped the 1.8/1.30 versions of capi/k8s in a release. i'd like to get back on track for regular updates and releases.
