Update examples for Connexion 3.0 #1615

This PR updates the examples for Connexion 3.0 and merges them for OpenAPI and Swagger.

2 examples required some changes to make them work:

  • The reverse proxy example required some fixes to the SwaggerUIMiddleware to leverage the root_path correctly. This is included in the PR.
  • The enforced defaults example requires the json validator to adapt the body and pass it on. We currently pass on the original body after validation, and I'm not sure if we should change this. I'll submit a separate PR to discuss this.

I see no reason to pass these to the app instead of to app.run directly.

Handle case when base path is "", which is the case both when endpoint is not part of an API, or when endpoint is part of the API registered on the root path.

We need a base path now that we're registering two apis on the same app.

Currently the parameter decorator uses a sync decorator when the view function is sync, even when the framework is async. This doesn't work as the async body cannot be read by a sync decorator.

the following example is targeted at FlaskApp would the same work out of the box by just replacing with AsyncApp ?
