fix: Correct Tavily MCP package name in documentation (#388)

The documentation incorrectly referenced @tavily/mcp which doesn't exist.
The correct package name is tavily-mcp, as confirmed by:
- The setup script already uses tavily-mcp@0.1.2
- NPM registry shows tavily-mcp exists
- @tavily/mcp returns 404 not found

This fix ensures users can successfully configure Tavily MCP server
by following the documentation.
