Code fence attribute and instrument type names in Metrics and Tracing docs

[antonfirsov]

Describe the issue or suggestion

As #43872 (comment) pointed out, the current state is problematic:

For example, here the instrument type was overlocalized:

https://learn.microsoft.com/cs-cz/dotnet/core/diagnostics/built-in-metrics-aspnetcore#metric-aspnetcoreroutingmatch_attempts

And here, Boolean was overlocalized:

https://learn.microsoft.com/cs-cz/dotnet/core/diagnostics/built-in-metrics-aspnetcore#metric-httpserverrequestduration

And in German, string is overlocalized:

https://learn.microsoft.com/de-de/dotnet/core/diagnostics/built-in-metrics-aspnetcore#metric-httpserverrequestduration

Russian is even worse:

https://learn.microsoft.com/ru-ru/dotnet/core/diagnostics/built-in-metrics-aspnetcore#metric-httpserverrequestduration

@cmastr This would be a good one for vendors. They could either code fence, use xref links, or add no-loc metadata.
