[JENKINS-55016] Disable flaky UtilTest.testDeleteRecursive_onWindows

It is getting in the way of other in flight PRs, so we should disable
to possibly take the time more serenely to fix this flakiness.

As 1.51 is upcoming, main goal here is to get an intermediate release
with 1.50 in case we have data in case things go wrong with one or another
and more quickly figure if this is likely to be coming from 1.50 or 1.51.
