Pull request for issue https://github.com/devonfw/devon4j/issues/468.
Removed the (devon4j) Spring specific stuff from the general guide and added it to a specific guide in the Spring subfolder. Also removed the existing Quarkus CORS guide as it describes the same as the official Quarkus guide. I have simply linked this guide into the general guide.
