datadogreceiver produces incorrect telemetry.sdk.language

What happened?

Description

Looks like DataDog's library uses ".NET" as value instead of "dotnet" in their instrumentation:

See: https://github.com/DataDog/dd-trace-dotnet/blob/ecb5d5949f6c29dbe99a451c7a3574013cfeb1bd/tracer/src/Datadog.Trace/AgentHttpHeaderNames.cs#L76

So we need to remap ".NET" to "dotnet" to follow OTEL semantic conventions.

I've also doublechecked other variables, and they seem to map to semantic conventions correctly -> https://opentelemetry.io/docs/specs/semconv/resource/#telemetry-sdk

The only other odd language is javascript. DD uses "javascript" in their instrumentation -> https://github.com/search?q=repo%3ADataDog%2Fdd-trace-js%20Datadog-Meta-Lang&type=code

But we don't seem to have equivalent in semantic conventions?
