fix: convert Prometheus histograms to non-cumulative otel histogram

[mehran-prs]

When we record a value using Prometheus histograms, it captures that value for that bucket and also previous buckets, but open telemetry histogram captures in a non-cumulative way, I mean it just captures for the matched bucket and doesn't add that value to the previous buckets.
This issue causes getting wrong histogram values when we use Prometheus bridge to send our data to open telemetry collector.
Please take a look at issue #4484 as an example of this issue.

Its fix was quick, so I made a PR, but let me know if I'm wrong or I should use the bridge in another way please.
