Describe the issue

Since this PR has been merged, we could improve DAB sample and add some documentation on how to correctly instrument the integration with OTEL.

Suggestion

Example should include OTEL instrumentation and doc should explain how it works

@aaronpowell should we start updating our readme and then align the official one on ms learn?

[aaronpowell]

Shouldn't the integration just set that up without you having to do anything?

[tommasodotNET]

Yes, but you need to configure the dab-config.json to use otel

[aaronpowell]

Given that DAB supports layering config files, would it make sense for us to generate that config and add it as "the last" config file that would get loaded?

That way it's not something you have to worry about configuring, it just gets added for you "magically" (and maybe we add an opt-out path if people don't want OTEL enabled)
