rke2 - ruling this out as too difficult to automate at this time. You would need to do the following:

• provision rke2 with vsphere chart enabled on the latest released version of rancher where the chart repo is still set to release-*
• upgrade rancher to an rc-d version of rancher (which should update the charts to dev-2.x)
• upgrade rke2 cluster
  the reason this ^ is necessary is because logic in rancher rke2 provisioning selects the latest chart version(s) available, so you can't select the version you want to install. Which means that you can't test upgrading the chart on the same rancher version for rke2 without doing so in the aforementioned manner
