task: upgrade to java 21.0.7 (dotCMS#32006)

This pull request updates the Java SDK version used in the `.sdkmanrc`
file for the dotCMS project. The change ensures the project uses a more
recent version of the Java SDK.

This jdk includes a fix to the issues we saw with running dotCMS in
docker on an m4 apple that required the `-XX:UseSVE=0` parameter in
order to run.
