Bump lombok, since it's not compatible with JDK21

There is error during compilation while running under JDK21:

java.lang.NoSuchFieldError: Class com.sun.tools.javac.tree.JCTree$JCImport does not have member field 'com.sun.tools.javac.tree.JCTree qualid'

Following advice from projectlombok/lombok#3393 seems to fix the issue
