[prometheus-elasticsearch-exporter] The "snapshot" default value does not match the exporter default

[seanhoughton]

Describe the bug a clear and concise description of what the bug is.

The default value for "snapshot" metrics is true in values.yaml. However, the default is "false" in the exporter itself. Running snapshot metrics very frequently creates large amounts of bucket requests which has been adding up to thousands of dollars for our team. This setting should default to "false".

Default in chart:
https://github.com/prometheus-community/helm-charts/blob/main/charts/prometheus-elasticsearch-exporter/values.yaml#L220

Default in exporter:
