Machine provisioning fails creating vnc client when using PROXMOX_TOKENID

[A clear and concise description of what the bug is.]

I used an API token to create a cluster. I set these env vars:

PROXMOX_PASSWORD=""
PROXMOX_SECRET=my-super-secret
PROXMOX_TOKENID=capmox@pve1!capmox1
PROXMOX_USER=capmox@pve1

then ran:

clusterctl generate cluster cappx-test --control-plane-machine-count=3 --infrastructure=proxmox:v0.3.5 --config https://raw.githubusercontent.com/k8s-proxmox/cluster-api-provider-proxmox/main/clusterctl.yaml > cappx-test.yaml

after applying that config, no machines are created and I see this in the cappx-controller-manager log:

@stenwt @robinelfrink
yes this is the know issue. this is came from proxmox side limitation. until proxmox support api token for vnc endpoint, please use user/pass instead. closing as duplicate #65
