Reproducible Comparison jobs fail as repro_diff.out is not available

[jiekang]

The jobs are failing to archive artifacts as file repro_diff.out is not found. This file was renamed to reprotest.diff as part of adoptium/temurin-build@ad4a1c3

Job sample: https://ci.adoptium.net/view/ReproducibleBuild/job/jdk21u-linux-x64-temurin_reproduce_compare/80/console

Sample log:

Archiving artifacts
‘**/repro_diff.out’ doesn’t match anything: ‘**’ exists but not ‘**/repro_diff.out’
[Pipeline] }
[Pipeline] // dir
[Pipeline] echo
No artifacts found that match the file pattern "**/repro_diff.out". Configuration error?
