Feature request: Support for a catch all route in Event Handler REST API

[sdangol]

Use case

Currently, the Event Handler supports specific route patterns, but there's no built-in support for catch-all routes that can handle arbitrary paths. This is useful for:

• Creating fallback handlers for unmatched routes
• Building proxy-like functionality where you want to capture all requests under a certain path
• Implementing wildcard routing patterns

Solution/User Experience

Add support for catch-all routes using regex patterns like .+ that can match any path. This would allow developers to create flexible routing patterns that can handle multiple path segments.

import { APIGatewayResolver } from '@aws-lambda-powertools/event-handler/resolvers';

const app = new APIGatewayResolver();

app.get('.+', () => {
  return {
    message: 'Hello, World!'
  };
});

export const handler = async (event, context) =>
  app.resolve(event, context);
