docs: Initialize tutorials section with MCP server example

This commit adds a new `tutorials.md` file to the CLI documentation.
This section is intended to house various tutorials for using Gemini CLI.

The initial content includes a tutorial on setting up Model Context
Protocol (MCP) servers, using the GitHub MCP server as an example.

The `docs/cli/index.md` has been updated to include a link to this
new tutorials section.

+
+## Setting up Model Context Protocol (MCP) Servers
+
+> **A Note on Third-Party MCP Servers:** Before using a third-party MCP server, ensure you trust its source and understand the tools it provides. Your use of third-party servers is at your own risk.
+
+### GitHub MCP Server
+
+The [GitHub MCP server] provides tools for interacting with GitHub repositories, such as creating issues, commenting on pull requests, and more.
+
+[GitHub MCP server]: https://github.com/github/github-mcp-server
+
+#### Prerequisites
+
+Before you begin, ensure you have the following installed and configured:
+
+- **Docker:** Install and run [Docker].
+- **GitHub Personal Access Token (PAT):** Create a new [classic] or [fine-grained] PAT with the necessary scopes.
+
+[Docker]: https://www.docker.com/
+[classic]: https://github.com/settings/tokens/new
+[fine-grained]: https://github.com/settings/personal-access-tokens/new
+
+#### Guide
+
+##### Configure the MCP Server in `settings.json`
+
+In your project's root directory, create or open the `.gemini/settings.json` file. Add the `mcpServers` configuration block to instruct Gemini how to launch the GitHub server.
+
+```json
+{
+  "mcpServers": {
+    "github": {
+      "command": "docker",
+      "args": [
+        "run",
+        "-i",
+        "--rm",
+        "-e",
+        "GITHUB_PERSONAL_ACCESS_TOKEN",
+        "ghcr.io/github/github-mcp-server"
+      ],
+      "env": {
+        "GITHUB_PERSONAL_ACCESS_TOKEN": "${GITHUB_PERSONAL_ACCESS_TOKEN}"
+      }
+    }
+  }
+}
+```
+
+##### Set Your GitHub Token
+
+Use an environment variable to store your PAT.
+
+```bash
+GITHUB_PERSONAL_ACCESS_TOKEN="pat_YourActualGitHubTokenHere"
+```
+
+Gemini CLI will automatically substitute the `${GITHUB_PERSONAL_ACCESS_TOKEN}` placeholder from your `settings.json` file.
+
+##### Launch Gemini CLI and Verify the Connection
+
+Gemini CLI will automatically read your configuration and launch the GitHub MCP server in the background. You can ask Gemini CLI to perform GitHub actions in natural language.
+
+```bash
+"get all open issues assigned to me in the 'foo/bar' repo and prioritize them"
+```
