Marcus Müller (@M-arcus), thx for the PR 👍

We do not fix links from code/core/guidelines and ADR here, as they are imported from shopware/shopware.

I will create an issue on the matter and we will see what is actually fixable and what should stay. Please remove the changes from the PR, and I will merge it ASAP. You are free to create a PR on shopware/shopware to fix those as well of course 🙂
