Subject: [PATCH] Docs: loki.md: Add example of Loki data source config
 (#29976)

* loki.md: Add example of Loki data source config

It was little difficult to search an example of setting datasourceUid for Jaeger data source.

I found the answer from https://github.com/grafana/grafana/issues/26087 and thought it would be good to document it.

+Here's an example of a Jaeger data source corresponding to the above example. Note that the Jaeger `uid` value does match the Loki `datasourceUid` value.
