Steps to reproduce or a small repository showing the problem:
I have 100,000 entity to save, I'd like to split them to 10 chunks, each chunk has 10,000 items. so what's the saveOption chunk should I pass? 10? or 10,000?
I check api document, it says 10,000, https://typeorm.io/#/repository-api/additional-options

I also check code, but the comments says it should be 10. https://github.com/typeorm/typeorm/blob/80d6f6628af01ae58152aea39fe30b819351f6be/src/repository/SaveOptions.ts
