OCP IPI Documentation appears to mix up references to IBM Cloud VPC (on x86_64) with IBM Cloud PowerVS. This can be confusing to users and misrepresents the status of both IBM Cloud providers.

4.12 and 4.13

OCP 4.12 Docs show that IBM Cloud VPC (x86_64) GA'd on 4.12 (table 16)

Yet OCP 4.13 Docs show that IBM Cloud VPC GA'd on 4.13 (table 18)

I believe IPI IBM Cloud PowerVS GA'd on 4.13 (not 100% certain on that, versus a 4.14+ GA), while IPI IBM Cloud VPC GA'd on 4.12, as 4.12 Docs mention.

I also noticed that within the 4.12 Docs, IBM Cloud Power is mentioned as a new feature, although I would expect IBM Cloud VPC should've been instead

This appears as expected in the 4.13 Docs, IBM Cloud Power, so that appears okay.
