setup_jck_interactives fails When using AQA_Test_Pipeline param TOP_LEVEL_SDK_URL: Error opening archive: ... temurin.zip

JDK unpacking fails on Mac:
```
12:40:48 tarBall is temurin.zip
[Pipeline] sh
12:40:48 + '[' -d /Users/jenkins/workspace/Test_openjdk20_hs_special.jck_x86-64_mac/../../jck_run/jdk20/jdk ']'
12:40:48 + echo true
[Pipeline] sh
12:40:50 + head -1
12:40:50 ++ pwd
12:40:50 + tar -tf /Users/jenkins/workspace/Test_openjdk20_hs_special.jck_x86-64_mac/openjdkbinary/temurin.zip
12:40:50 tar: Error opening archive: Failed to open '/Users/jenkins/workspace/Test_openjdk20_hs_special.jck_x86-64_mac/openjdkbinary/temurin.zip'
[Pipeline] sh
12:40:51 + '[' -d /Users/jenkins/workspace/Test_openjdk20_hs_special.jck_x86-64_mac/../../jck_run/jdk20/jdk/ ']'
12:40:51 + echo true
```

Start by locating setup_jck_interactives and the AQA_Test_Pipeline handling of TOP_LEVEL_SDK_URL; inspect how temurin.zip is selected and passed to tar on Mac. Done means the JDK archive is found and unpacked successfully in the shown jdk20 path, without the archive-open error.
