docs: Add Neon MCP Server tutorial

[andrelandgraf]

This PR adds the Neon MCP server to the MCP docs.

• add neon-mcp.md tutorial to mcp docs
• documents two configuration setups: Remote MCP (streamable HTTP) or Local MCP (npx)
• lists three examples prompts & outputs for illustration purposes

Hey team, not sure if I need to register the extension somewhere else for this to work. Please let me know, happy to make the required changes :)

Hi @andrelandgraf, thanks for your contribution!

I proposed some changes to sync with the Tabs pattern we use for extensions with two install methods. Mostly I moved around your content and added some new text/structure:

• Top-level remote and local tabs
• Remote configuration steps section
• Local setup TLDR tip

I also added a "local development only" warning (based on the Neon server readme) and a servers.json entry. Note that I used the local install command for now bc there seems to be an issue with streamable install links.

[dianed-square]

Using the local command install method until the streamable install link works. I set endorsed to false because this was listed as an experimental Neon project, but you can change it to true if it's considered stable

[andrelandgraf]

Thanks so much for the help. I swapped it to true. MCP is still very new, so we caution people to use it as the protocol and our server may change and sensible use is required for production databases but otherwise, it's definitely ready to use!
