OCPBUGS-83862: Add conditional update risk for 4.21.0-25 from 4.20.z < 4.20.25

[shahsahil264]

Summary

Add type: Always conditional update risk for all existing 4.21.z GA releases (4.21.0 through 4.21.25) warning clusters upgrading from 4.20.24 or earlier about the Auto Node Sizing issue.

Context

PR #9494 raises minor_min from 4.20.15 to 4.20.25 for future 4.21.z builds. However, all existing 4.21.z releases were built with the old minor_min, so clusters on 4.20.0-4.20.24 can still see upgrade paths to them.

Per Scott Dodson and W. Trevor King, these existing versions need a conditional update risk to warn affected clusters.

Bug

OCPBUGS-83862: During upgrade from pre-4.20.25, auto-sizing-disabled MachineConfigs override KubeletConfig autosizing settings on custom MachineConfigPool nodes. Fixed in 4.20.25 via openshift/machine-config-operator#5885.

Risk details

• from: ^4[.]20[.](1?[0-9]|2[0-4])[+].*$ — matches 4.20.0 through 4.20.24
• type: Always — affects all clusters upgrading from the unpatched version range
• 26 files: one per GA 4.21.z release (4.21.0 through 4.21.25)

Companion to #9494.
