[RUN-5271] Rename tracing-in-runtime to opentelemetry-in-runtime

[atennapel]

Since we are adding logs as well to the OpenTelemetry support the page is more accurately named opentelemetry-in-runtime.

Thanks for the PR,
I've fixed some broken links and added an alias in case people had bookmarked the previous version - was it linked anywhere outside the documentation?
Can you check f6e5486 to make sure it still looks OK. Then I can merge it.

[atennapel]

Thanks! It was not linked anywhere outside of the docs, as far as I could find.
Your commit looks good. But someone from my team still needs to do a review, I will ask someone.

Perhaps...

Suggested change

	Mendix Tracing uses [OpenTelemetry](/refguide/opentelemetry-in-runtime/) to send Mendix Runtime traces to [Datadog APM](https://docs.datadoghq.com/tracing/), giving you distributed tracing visibility into your app's performance and microflow executions.
	Mendix uses [OpenTelemetry](/refguide/opentelemetry-in-runtime/) to send Mendix Runtime traces to [Datadog APM](https://docs.datadoghq.com/tracing/), giving you a preview of your application performance and microflow executions.

"giving you insight into" perhaps? I don't like the word "preview" because it might imply that there's a more elaborate view of your apps performance, which there is not.
@MarkvanMents what do you think?

[akkrishnakumar]

Sure. That will also do.
