Fix histogram for dns.lookup.duration

[Kielek]

Related to dotnet/runtime#92917.

I do not think that it is worth to keep support for .net8-rc/unstable. It should be fine to support only GA version.

Changes

Update metric name for DefaultHistogramBoundShortMappings. I do not think that it needs Changelog entry.

Merge requirement checklist

Failing tests seems to be not related to changes.
