Versions not adjusted for tags

[noracamillaa]

I tried following the course and cloned the git repo.
Running the playground main worked fine in the master branch.
When I did a check out on the start tag, as shown in the course Welcome video, I get errors in the build (same as here: https://stackoverflow.com/questions/73357109/class-java-lang-unsupportedoperationexception-cannot-be-cast-to-class-xsbti-full). Updating the versions fixed the issue for me.
