preliminary testing with make test-e2e, need to fixup the templates to use kubernetes 1.28.

Haven't tested - but the changes look good to me.

As a heads up - for the CAPI 1.7 bump the api versions and cluster api imports will need to be bumped so it'll end up being a substantial change.

thanks for the heads up @killianmuldoon !
