In 4.14 and 4.15 docs.openshift.com under the 3rd point of the Updating the virtual hardware for template on vSphere section there is an outdated hyperlink which push to download a whole ZIP file with all the vmware documentation called: Convert a Virtual Machine to a Template in the vSphere Client:
https://docs.openshift.com/container-platform/4.14/updating/updating_a_cluster/updating-hardware-on-nodes-running-on-vsphere.html#update-vsphere-virtual-hardware-on-template_updating-hardware-on-nodes-running-in-vsphere

The wrong link point to: https://docs.vmware.com/en/VMware-vSphere/6.0/com.vmware.vsphere.hostclient.doc/GUID-846238E4-A1E3-4A28-B230-33BDD1D57454.html

Which is an actual not vSphere supported version.

The link got changed by vmware back in Aug 2023: https://web.archive.org/web/20230601000000*/https://docs.vmware.com/en/VMware-vSpher[...]hostclient.doc/GUID-846238E4-A1E3-4A28-B230-33BDD1D57454.html

As the procedure for vSphere 7 is only:
Right-click the virtual machine and select Template > Convert to Template

We could just get read if the hyperlink, provide the simple steps with a disclaimer that it may change in different vSphere versions.
