topologySpreadConstraints should be an array

[gjacquet]

In opentelemetry-collector Helm chart, topologySpreadConstraints should be an array rather than an object as it is an array in Kubernets API: https://kubernetes.io/docs/concepts/scheduling-eviction/topology-spread-constraints/#topologyspreadconstraints-field

This seems to be causing this error when configuring topologySpreadConstraints:

ERRO[0000] [generateHelm] : values don't meet the specifications of the schema(s) in the following chart(s):
