[feature request] Support for adding default tags to specific Tracer

[ailn]

Package

OpenTelemetry

Is your feature request related to a problem?

For example, I have multiple instances of an app which have different configurations. I'd like to tag those differences in spans. The request is similar to this one (dotnet/runtime#84321) but for tracing.

What is the expected behavior?

In .net9 System.Diagnostics.ActivitySource got new ctor overload which has the 'tags':
public ActivitySource(string name, string? version = "", IEnumerable<KeyValuePair<string, object?>>? tags = default)

Please add similar overload to TracerProvider.GetTracer

Which alternative solutions or features have you considered?

I can use System.Diagnostics.ActivitySource but I'd like to use the shim.
