No AggTemp column in otel.otel_metrics_histogram Table

What happened?

Description

The otel.otel_metrics_histogram table has no AggTemp column, so it is impossible to tell the difference between Delta and Cumulative metrics stored in this table.

Steps to Reproduce

Expected Result

AggTemp in the otel.otel_metrics_sum table is stored from the metric.AggregationTemporality(). The same should be the case for otel.otel_metrics_histogram

Actual Result

No AggTemp column in otel.otel_metrics_histogram.

Collector version

v0.102.0

Environment information

No environment information necessary. This affects all environments.

OpenTelemetry Collector configuration

Any implementation of the clickhouseexporter would have this bug.

Log output

N/A

Additional context

Current otel.otel_metrics_histogram schema: https://github.com/open-telemetry/opentelemetry-collector-contrib/blob/main/exporter/clickhouseexporter/internal/histogram_metrics.go#L21-L60

Current otel.otel_metrics_sum schema: https://github.com/open-telemetry/opentelemetry-collector-contrib/blob/main/exporter/clickhouseexporter/internal/sum_metrics.go#L21-L57

I am planning on opening a PR to fix this as well.
