[STAC-25140] Requirement docs are confusing (minimum node size and minimum node count)

STAC-25140

The minimum node size and minimum node count lead to confusion now. In at least one case it resulted in the expectation that (minimum node count) * (minimum node size) is all that’s required. Which is obviously incorrect. For example for trial: minimum node is 4vCPU and 8Gi memory, minimum count is 1, but a few rows higher it says memory requirement is 23.4Gi.

TBH I head to double check the table and the call-out underneath too to get the exact intention which is this (my words):

The minimum node size means that the nodes in the k8s cluster need to be at least of that size. The minimum node count means you need at least that amount of nodes. That doesn't mean you need only 1 node of minimum size (it still needs 23.4Gi of memory).

For HA deployments minimum node count is 3 because databases run with 3 replicas and they should run on 3 different nodes. Minimum node size can increase because there is a single pod that requires now that amount of memory or CPU.
