The wrong json package was used, resulting in patches being unmarshaled with numbers as float64 rather than int64. This in turn confused HasConflicts() which expects numeric types to match.

The end result was false positives of meaningful conflicts, such as:

there is a meaningful conflict (firstResourceVersion: "8517", currentResourceVersion: "8519"):
 diff1={"metadata":{"resourceVersion":"8519"},"spec":{"replicas":0},"status":"conditions":null,"fullyLabeledReplicas":null,"replicas":0}}
, diff2={"spec":{"replicas":0}}

This is branched from a discussion on #43469.

Fix false positive "meaningful conflict" detection for strategic merge patch with integer values.
