🚀 Feature: Add docs for local grafana tempo integration

[henryxparker]

Which component is this feature for?

Anthropic Instrumentation

🔖 Feature description

An addition to the grafana tempo docs that includes instructions on how to connect it with a local grafana instance.

🎤 Why is this feature needed ?

I'm evaluating traceloop for my team. I don't have much grafana experience and so trying to get this working with a local version of grafana has honestly been an absolute nightmare. (even though I know it should have been really simple)

✌️ How do you aim to achieve this?

Add a blurb under the "Without Grafana Agent" section: If you are running tempo locally set the environment variable to point to tempo's http ingest port

default: TRACELOOP_BASE_URL=0.0.0.0:4318
