Add: RedHat-Middleware-Workshops/spring-to-quarkus-todo (Spring Boot -> Quarkus)

https://github.com/RedHat-Middleware-Workshops/spring-to-quarkus-todo

`This tutorial takes a Spring Boot application using Spring MVC, Spring Data JPA, and a PostgreSQL database and converts it to Quarkus with little-to-no source code changes. It uses the [Red Hat Migration Toolkit for Applications](https://developers.redhat.com/products/mta/overview) to analyze the Spring Boot application and offer suggestions for how to migrate it to Quarkus`

Start by reviewing the linked spring-to-quarkus-todo tutorial and its Spring Boot, Spring MVC, Spring Data JPA, and PostgreSQL components. Determine how the example should be added to the konveyor/example-applications repository and what migration analysis or runnable application criteria define completion.
