Add coverage for the quarkus-spring-boot-properties Quarkus extension

Exploratory testing for the `quarkus-spring-boot-properties` Quarkus extension. The application consists of a REST endpoint
with some different approaches to inject properties.

Current limitations:
- Relaxing name convention is not supported and it won't be supported: quarkusio/quarkus#12483
- The annotation `@ConstructorBinding` is not supported yet: quarkusio/quarkus#19364
