Update min version for health node reporting to 8.5 (#90365)

The health node and disk health reporting (via the health node) was enabled
starting with 8.5.
Some version checks were still on 8.4 (when this feature started being developed).
This can create failures in mixed cluster environments.

This updates the min version for the health node reporting functionality to 8.5
