Refactor "removed" code
In https://git.higidi.com/Automated-TYPO3-Update/automated-typo3-update/blob/99e38e43afe22eb5b6bfe48a5af1c2d0de1d0681/src/Standards/Typo3Update/Sniffs/Removed/AbstractGenericUsage.php#L159 we have to "save" the removed entries for later usage. The current place is just wrong and by implementing further classes you always forget to put this logic into this method.
We should find a better way.
E.g. a dedicated method which is abstract? We can overwrite it for the one class where the current solution works.
