[Agents] Clarify that the Cloudflare API MCP server is the only one you need

[neelakolkar-cf]

Summary

Closes #31749.

The Cloudflare's own MCP servers page did not make clear that https://mcp.cloudflare.com/mcp is the only MCP server most people need. It also described the server as having "just two tools", which is out of date since the server gained a docs tool in cloudflare/mcp#148.

This PR addresses the review feedback on #31750, which was closed as stale before the feedback was applied (#32726 later restored the original #31750 diff without these changes):

• Cloudflare API MCP server intro: states that https://mcp.cloudflare.com/mcp is the only MCP server you need, as plain text rather than a tip callout, and without mentioning the product-specific servers.
• Tools: documents the docs() tool for searching Cloudflare developer documentation alongside search() and execute().
• Product-specific MCP servers: uses the suggested intro marking these servers as optional.

The Product-specific MCP servers heading is unchanged, so the existing #product-specific-mcp-servers link from the 2026-07-28 Agents changelog entry keeps working.

Documentation checklist

• The change adheres to the documentation style guide.
