Just like the Spring Boot one does:

These properties are supported in Spring's `application.properties`:

optaplanner.solver-manager.parallel-solver-count::
The number of solvers that run in parallel.
This directly influences CPU consumption.
Defaults to `AUTO`.

To avoid duplication. We might be able to restructure that doc to just have a section "application.properties" below the Spring Boot chatper and have both Quarkus and Spring Boot link to that section?
(If properties are Quarkus or Spring Boot only or behave differently, that should be clearly marked as such.)
