Creating a Node - Ubuntu Image is not described

[uli-max]

Issue on page: https://github.com/opentelekomcloud-docs/cloud-container-engine/blob/main/api-ref/source/apis/cluster_management/creating_a_node.rst

Ubuntu image is missing in api-documentation.
Table 5 / os
String is "Ubuntu 22.04"
Maybe add also a comment, that Ubuntu is only available in "Tunnel Mode"

Once this is resolved I will update the terraform docs.

tunnel restriction in the UMN

https://docs.otc.t-systems.com/cloud-container-engine/umn/nodes/node_oss.html
