[DOC] Update query-editor.md

[knylander-grafana]

What this PR does:
Preparing to share the content from the query editor page to the Cloud and the Grafana docs. This update:

• Changes the image calls from the TraceQL query editor page to use the asset storage in GCP instead of local storage
• Removes calls to specific Tempo versions
• Adds a few words about Grafana Cloud vs Grafana

@jdbaldry This is the information on the query editor that we talked about sharing to Grafana and Grafana Cloud docs.

Nice, do we know at which URL paths we want to see this content?

We could use Hugo mounts for this, or our docs/shared shortcode.

The former has the downside that we need to make sure we remember that this content is reused in multiple places. Perhaps we can annotate the file with some information in the front matter?

[knylander-grafana]

@jdbaldry this content will probably need to be in Grafana Cloud in the Traces data sources section and in Grafana in the Tempo query section. We might be able to just share the file to those other areas.

So that would be /docs/grafana-cloud/data-configuration/traces/query-editor/ and docs/grafana/latest/datasources/tempo/query-editor/?
I noticed that the latter already exists (https://grafana.com/docs/grafana/latest/datasources/tempo/query-editor/), are we replacing it?

Yes.

docs/grafana/latest/datasources/tempo/query-editor/? I noticed that the latter already exists (https://grafana.com/docs/grafana/latest/datasources/tempo/query-editor/), are we replacing it?

@jdbaldry For now, I wouldn't replace the existing query-editor page. I am adding other content for the query editor that will be added to that page in datasources/tempo/query-editor.
