In case you wonder, I messed up with the branches, but it should be fine now.
To implement this story, I used filewalkers, which I know you removed in the other code sections.
I tried it otherwise but I was not able to fix it. Now it works, but you have to decide whether you want this kind of implementation or not.

@leonrohne27 thanks for your PR.
The actual updating of the properties file looks already good to me. 👍
However, the way you try to find the properties is not correct.

It is required that you first read and understand the documentation of the related feature:
https://github.com/devonfw/IDEasy/blob/main/documentation/repository.adoc

p.s.: I took a shortcut even though this PR was in team review state to speed up our progress.

@leonrohne27 thanks for your rework. I resolved all existing review comments 👍

Looking at the PR again I found a small problem that I solved with a constructive suggestion.
If you agree and commit it, we can merge this. Thanks.
