Jakarta Batch Job parameter `purgeAllOnStart` will purge all documents instead of just the ones specified in `entityTypes`

With purgeAllOnStart set to true, a scope for Object is created https://github.com/hibernate/hibernate-search/blob/b14da95643384d9f2443a34f827d70a43007f523/mapper/orm-jakarta-batch/core/src/main/java/org/hibernate/search/jakarta/batch/core/massindexing/step/beforechunk/impl/BeforeChunkBatchlet.java#L66-L67 Instead of the scope being limited to the entities defined in the entityTypes job parameter, more entities are potentially being removed than the entityTypes required.
