[node] fix warning

[BulatSaif]

Fix for warning during node deployment:

coalesce.go:286: warning: cannot overwrite table with non-table for node.node.keys (map[])

Solution: Ensure that node.node.keys is defined consistently as a list in values files. Check and update values files to avoid conflicting data types for node.node.keys.
