Affects all versions of our documentation.

2 issues:
a) the wording that was introduced with https://issues.redhat.com/browse/OCPBUGS-23201 is ambiguous
b) release notes were not fixed when https://issues.redhat.com/browse/OCPBUGS-23201 was fixed

-----------------------------------------------------------

For a):
Issue description:

Pages such as https://docs.openshift.com/container-platform/4.14/machine_management/adding-rhel-compute.html (and others) state the following:

Base OS: RHEL 8.6 and later with "Minimal" installation option.

That's an ambiguous statement. One can either read it so that any minor version of RHEL 8 after 8.6 is supported. More likely though is that one will read it like this: any version >= 8.6 is supported, and 9.2 >= 8.6 so it's supported.

Suggestion:

Base OS: RHEL 8 starting with minor version 8.6 and later with "Minimal" installation option.

Add a note *Important* the same as for RHEL 7: "Adding RHEL 9 compute machines to an OpenShift Container Platform cluster is not supported"

-----------------------------------

For b)

Each OCP release-notes state that:

OpenShift Container Platform 4.12 is supported on Red Hat Enterprise Linux (RHEL) 8.6-8.9 as well as on Red Hat Enterprise Linux CoreOS (RHCOS) 4.12[1].
OpenShift Container Platform 4.13 is supported on Red Hat Enterprise Linux (RHEL) 8.6, 8.7, and 8.8 as well as on Red Hat Enterprise Linux CoreOS (RHCOS) 4.13[2].
OpenShift Container Platform 4.14 is supported on Red Hat Enterprise Linux (RHEL) 8.6, 8.7, and 8.8 as well as on Red Hat Enterprise Linux CoreOS (RHCOS) 4.14[3].
OpenShift Container Platform 4.15 is supported on Red Hat Enterprise Linux (RHEL) 8.8 and 8.9, and on Red Hat Enterprise Linux CoreOS (RHCOS) 4.15[4].
OpenShift Container Platform 4.16 is supported on Red Hat Enterprise Linux (RHEL) 8.8-8.10, and on Red Hat Enterprise Linux CoreOS (RHCOS) 9.4[5].

Suggestion:
Use the wording of our support policy in the release notes.

Just reiterating our policy, at OCP minor version GA we test and support the two latest RHEL 8 minor versions for RHEL workers. All subsequently releaesed RHEL 8 minor versions are supported as they ship until the OCP version goes EOL. 4.10 went EOL before RHEL 8.9 ships but 4.11+ are still supported.

So something like this, example 4.14:

OpenShift Container Platform 4.14 is supported on Red Hat Enterprise Linux CoreOS (RHCOS) 4.14 as well as on Red Hat Enterprise Linux (RHEL) 8.6, 8.7, and any subsequent version of RHEL 8 which is released before End of Life of OpenShift Container Platform 4.14.
