Introduced configuredAuthServer that only requires .env BASE_URL entry

[sagara-gunathunga]

Purpose

This introduces an easy configuration option for simple MCP server development.

No need to configure McpAuthServer; instead, only the following two changes are enough:

1. Import configuredAuthServer**

import { configuredAuthServer as auth } from '@asgardeo/mcp-express';

2. Set up BASE_URL in the .env file

BASE_URL=https://api.asgardeo.io/t/<your-org>
