Fix ./gradlew spotlessApply fail groovy check

[Abacn]

Tested by run ./gradlew spotlessApply

The issue is similar to diffplug/spotless#1572 but as apache/kafka#13205 noted, new version of spotless plugin dropped support of java8. The workaround is needed for current spotless plugin run in gradle 8
