What this PR does / why we need it:

Lots of AI in Dataverse land! Preview the new AI Guide at https://dataverse-guide--11541.org.readthedocs.build/en/11541/ai/index.html

Which issue(s) this PR closes:

• Closes AI Guide #11540
• Closes Create an MCP server for Dataverse #11474

Special notes for your reviewer:

• Am I forgetting any Dataverse-related AI efforts? 🤔 I wrote up the ones that came to mind. 😅
• I started a thread on where the AI Guide should be placed in the side bar. How high up, I mean.
• I really like this blog post about MCP: https://www.anildash.com/2025/05/20/mcp-web20-20/
• I'm asking the Documentation Working Group about it here: https://dataverse.zulipchat.com/#narrow/channel/446770-docs/topic/AI.20Guide/near/521354579

Suggestions on how to test this:

For the MCP section, I'd suggest trying to get at least one of the MCP clients working. I had pretty good luck with Cursor, Visual Studio Code, and Windsurf but had a little trouble with Zed. The docs are here: https://github.com/gdcc/mcp-dataverse

Is there a release notes update needed for this change?:

Yes, added.

I put the AI Guide third, after User and Admin. But maybe it should be second, after User? 🤔

Looks fine - good to collect all the latest work in AI. The only minor suggestion I would have is to add some standard AI cautions - these are all new/experimental, you're mileage may vary, rapidly evolving, ... - not worth holding the PR up for though. Once this is in. it can be improved as we do with any guide material.
