If the directory already exists from restored cache, the stage fails with `File exists`. ## Replay Test - https://do.pingcap.net/jenkins/blue/organizations/jenkins/pingcap%2Ftiflash%2Frelease-8.5%2Fpull_unit_test/detail/pull_unit_test/356/pipeline/ 2026-03-26 03:53:18 +00000eba514cad2b3b65ecd0acde5615ddedcab1ea11fix(pipelines): make tiflash release-8.5 ut cache prepare idempotenteditpipelines/pingcap/tiflash/release-8.5/pull_unit_test.groovygithttps://do.pingcap.net/jenkins/user/noreplynoreply
