Fix MCP servers settings location: under Copilot > Cloud Agent

[Ameausoone]

Why:

Closes: #45011

What's being changed (if available, include any code snippets, screenshots, or gifs):

The repository-level MCP configuration steps referenced a separate MCP servers sidebar item under repo Settings > Copilot. In the current UI, that setting is actually under Copilot > Cloud Agent, in the "Model Context Protocol (MCP)" section. Updated both occurrences of the navigation steps in configure-mcp-servers.md to match.

@Ameausoone This looks correct based on my own account, but it looks like it needs to be rebased.

@Ameausoone Looks like we're actively working on these docs, so I'm not going to ask you to rebase again yet. 😅 I'll just put a "ready to merge" on it and wait until we're done working on them.

@Ameausoone - Your change doesn't match what I'm seeing in the repo settings:

There is a separate page for the MCP JSON, so the currently published instructions are correct for the GUI I'm seeing.
