jtreg retrieval for jdk25u is failing with a checksum error

Example from https://ci.adoptium.net/job/Test_openjdk25_hs_extended.openjdk_riscv64_linux/7/console (Previous job #6 has the same problem, so this seems relatively recent)

This is potentially related to https://github.com/adoptium/ci-jenkins-pipelines/pull/1186 which was merged on Feb 23rd.

Also noting that https://ci.adoptium.net/job/dependency_pipeline/1464/ does not seem to have passed since November 7th.

The temurin-sbom phase has also been failing in addition to jtreg although that is likely to be fixed by https://github.com/adoptium/ci-jenkins-pipelines/pull/1191
