Integrate solr-mcp into the Solr Ref Guide

The Solr Ref Guide is where we direct folks to learn about Solr. https://solr.apache.org/guide/solr/latest/index.html.

We should integrate solr-mcp into the ref Guide. Maybe a Tutorial? Maybe a similar page to https://solr.apache.org/guide/solr/latest/getting-started/solr-admin-ui.html? I can imagine that solr-mcp enables a new very common pattern for interacting with Solr.

Review the Solr Ref Guide at the linked URL and the solr-mcp project to understand the current documentation structure and usage. Decide whether the integration should be a tutorial or a page similar to the Solr Admin UI guide; done means the chosen Ref Guide content is published and explains the common solr-mcp interaction pattern.
