Update graphql java 24.2

[geichelberger]

This updates graphql-java to the latest version 24.1 and tries to fix the breaking changes.

Thanks for the PR @geichelberger,

Our current plan is to do a v21.5.1 release, including #310 by @anttip, and then review/merge this PR and release (?).

I updated the PR as a new graphql-java version was released with a minor bug fix.

This is a small bugfix release, to use the latest version of DataLoader that includes nullability annotation improvements.

Hi @geichelberger
Thank you very much for your contribution! 🙏

Could you please rebase your branch onto the latest main? This will ensure you benefit from the recent CI/workflow fixes and allow the tests to run properly on your PR.

Additionally, could you update the version in gradle.properties to 24.2 instead of 24.1?

Once these changes are made, we should be able to proceed with the approval and merge.
Thanks again for your efforts!
