docs: Update installation link for Cursor MCP

[alsotang]

move args from command prop to args, which would be more standardized.

from {"command":"npx -y chrome-devtools-mcp@latest"} to {"command": "npx","args": ["-y", "chrome-devtools-mcp@latest"]}

Thanks for creating this! I used Cursor's tool to generate the config and i'd prefer to stick with what their recommend way. I'll close the PR for now (nevertheless I agree with your PR in that this is the more standard way).
