never ending check on nasty bash script

[judovana]

Describe the bug
The jscpd analyse of the https://github.com/judovana/temurin-build/blob/907db529f3b22973aec895e672db8eec0842eb87/tooling/compare-builds.sh is never finished (https://github.com/adoptium/temurin-build/actions/runs/11775432014/job/32795868920?pr=4008)

   sudo  npm install -g jscpd
   npx jscpd -v compare-builds.sh 

Is deadlocking the same.

With a bit of playing I found the guilty part of
https://github.com/judovana/temurin-build/blob/907db529f3b22973aec895e672db8eec0842eb87/tooling/compare-builds.sh#L394-L465 however checking that part alone do not cause infinite execution.

To Reproduce
Steps to reproduce the behaviour:

1. wget https://raw.githubusercontent.com/judovana/temurin-build/907db529f3b22973aec895e672db8eec0842eb87/tooling/compare-builds.sh
2. npx jscpd compare-builds.sh

Expected behavior
The analyse will finish in real time

Desktop (please complete the following information):

• OS: fedora 39 and github actions
• NodeJS Version: github actions and 10.8.2
• jscpd version: github actions and 4.0.5

Small note. I was unable to pinpoint the culprit. The deadlock was there no meter what I did. I had to split the file to two to make it pass.
