Multiple Temurin Build Ref entries causing parse error in ./linux_repro_build_compare.sh

[sxa]

What are you trying to do? Run ./linux_repro_build_compare.sh

Expected behaviour: Comparable build is run

Observed behaviour: Job fails to pick up the temurin-build sha because there are multiple entries for it (one for each of the final artifacts) after #3529 was merged

Any other comments: Noting that the process is currently broken for GA releases due to the SHAs for the old temurin-build repository not matching the current CycloneDX ones after it was updated in #3558
