Jenkins runs with obsolete java 21, causing errorprone errors

[dweiss]

Description

We get odd errors from errorprone that don't reproduce on main. This is due to JDK-8225377; jenkins has a very old JDK 21 release and that's why this happens there.

https://issues.apache.org/jira/browse/INFRA-28365

I'll temporarily disable this error prone check on 10x.
