Update README.md - Broken link

[sandraros]

The link "learning journey" in this page:
               

goes to a 404 page:
https://learning.sap.com/learning-journeys/sapui5-development-learning-journey

I guess it should go to this page:
https://learning.sap.com/learning-journeys/develop-sapui5-applications
