Description

When creating a System.Diagnostics.Metrics.Meter with a version and tags, e.g.

var meterTags = new KeyValuePair<string, object>[]
        {
            new KeyValuePair<string, object>("meterKey1", "value1"),
            new KeyValuePair<string, object>("meterKey2", "value2"),
        };
var meter = meterFactory.Create("Test", "1.0.0", meterTags);

The version and tags provided do not show up in Prometheus exported metrics.

Steps to Reproduce

I have a branch of this Repository with one of the integration tests edited to show this issue, you can find the branch here: main...ProbablePrime:opentelemetry-dotnet:prime/tests/meter-tags

Expected Result

I expect, the Meter sourced tags to be included in the output. This is shown in the test case expected data changes.

E.g. counter_double_bytes_total{{otel_scope_name='{MeterName}',otel_scope_version='{MeterVersion}',**meterKey1='value1',meterKey2='value2'**,key1='value1',key2='value2'}}

Actual Result

It results in a failed test.

Additional Context

I apologize for any terminology goofs, here. I'm brand new to the OpenTelemetry scene. Please ask questions if you are unsure.

This is based on:

• Meter Tags and Prometheus HttpListener #5829 (reply in thread)
• https://stackoverflow.com/questions/78806211/how-to-have-the-prometheus-exporter-export-labels-tags

Which may have additional information to help.

Thank you!
