Add ErrorTracker to the guides

[odarriba]

This change proposal adds ErrorTracker to the guide that lists integrations that use Oban.Telemetry to integrate out-of-the-box with Oban.

In the case of the ErrorTracker, it uses Telemetry events to catch and store context and exceptions of Oban jobs executed on the system.

I was not sure if I should have add it to the Error tracking section, as it does not require any special module to handle the exceptions.

Should I add a sentence there explaining that it can be done with the ErrorTracker library, or even linking to the file that we use as a Telemetry handler as an example?

Thanks for your awesome work on Oban 🙌

Yes please. Alongside Sentry and AppSignal would be excellent.
