@aBega2000 thanks for your PR. 👍
I have nothing to add to what @slskiba already left as review comments. Please address these review comments. Then we can resolve and merge.

@aBega2000 Thanks for your rework and improvements. 👍
Still it turns out some details are not yet clear and your implementation needs further rework.
I left several review comments for you to address.
As I cannot put a review comment on an empty file:
Please try to avoid inconsistent test-data except for cases where you explicitly want to test how the software behaves in case or corrupt data.
A Empty file is not a valid JSON file.
Simply put {} into extensions.json and you are safe.
Your current "hack" code migrated from bash would also in this case insert `"extensions": "plugin1,plugin". This may let your JUnit pass but this is still invalid JSON and the real VSCode application would complain about it.

@aBega2000 thanks for your rework. Looks very good already. 👍

One review comment was still not completed and I added some small hints for final improvement. We can merge when these are resolved.
