Dependency update OpenTelemetry ver. 1.11.0-rc.1

[snakefoot]

One might consider making this NLog target a wrapper around the public OpenTelemetryLoggerProvider.

Then "just" inject a special LogEvent-state-object that includes the NLog LogEventInfo-properties. Maybe consider making a pull-request so one can override the checking of global/static property Sdk.SuppressInstrumentation:

    public bool IsEnabled(LogLevel logLevel)
    {
        return logLevel != LogLevel.None && !Sdk.SuppressInstrumentation;
    }

I'm not sure what the purpose of this change is. The SpanId and TraceId fields of LogRecordData are populated whenever you create an instance.

As for your other suggestion, are you suggesting that we create an instance of OpenTelemetryLoggerProvider instead of LoggerProvider and use that to create instances of ILogger instead of OpenTelemetry.Logs.Logger? I think I considered that initially, but it looks like the public constructor for OpenTelemetryLoggerProvider will eventually be obsoleted when the API I'm using becomes stable.

I suppose we could use it as a temporary workaround until bridge API becomes stable, but I would rather avoid it. Either way, I asked the OpenTelemetry team here if they have an ETA on when the bridge API becomes stable, so we will see what they say.

Believe it will always be possible to build a local Microsoft LoggerFactory (isolated instance inside OtlpTarget), and then add OpenTelemetry as Logging-Provider. Then let OtlpTarget perform "logging" to its own local Microsoft LoggerFactory.

Yes you are right. It was only because I saw OpenTelemetryLoggerProvider explicitly assign SpanId + TraceId, but I guess it is because it doing object-pool-rent.

I have now changed the pull-request to just be dependency update, and fixing of some build warnings.
