[Demo] Add info about React Native app

[jpmunz]

This updates the demo documentation to include the React Native example app that was added here: open-telemetry/opentelemetry-demo#1781

Preview: https://deploy-preview-5704--opentelemetry.netlify.app/docs/demo/services/react-native-app/

thanks, looks good overall, a few comments

[chalin]

As a general comment, I don't think that the app should be documented as a part of the demo/services. Even the entry in the index page reads, "React Native mobile application that provides a UI on top of the shopping services."

How does it relate to the Collector?

Maybe we need a new Demo top-level entry?

I actually disagree @chalin.
The app is just another way to interact with the demo.
The user can navigate to the frontend and buy astronomy stuff, or they can open the app and do the same.
The app should be on the same level as frontend-proxy, which is the service that exposes the frontend.

How does it relate to the Collector?

As well as the other services, the reactive-native-app is instrumented with OTel and sends traces to the Collector.

I agree with @julianocosta89 here. The react-native-app could be seen similar to the frontend service. It the mobile app does route all its telemetry data through the frontend-proxy into a collector, and does similar API calls as the web tier does.

Marking this as Ready to Review now that the associated PR in the demo repo got merged: open-telemetry/opentelemetry-demo#1781 (comment)

Will updated and take a look at the check failures

[jpmunz]

I'm not quite sure how to address the failure on the "Build and Check Links" check, it appears to fail on running npm run _diff:fail which exits successfully for me locally

IMPORTANT: (RE-)RUN /fix:all to ensure that there are no remaining check issues.

I think the issue is fixed, but the CI checks need to be triggered again. Maybe try a rebase?

@jpmunz @tiffany76 let's ignore the build issues for now, we can fix them once the PR is approved by @open-telemetry/demo-approvers and @open-telemetry/docs-approvers and before we merge it

	The JS OTel packages are supported for node and web environments. While they
	work for React Native as well they are not currently explicitly supported for
	that environment and may break compatibility with minor version updates or
