📝 Document `.in_()` method

[masylum]

Hi there! I'm pretty new to this project and I think this is the best time to contribute documentation. The tutorial is amazing, but missing a formal reference makes finding some advanced features a bit difficult. For instance, since I'm still not 100% sure how the integration with SQLAlchemy works, I had to search how to do in_. I found this issue here https://github.com/tiangolo/sqlmodel/issues/353 which explains perfectly how to do it.

I've went ahead and added the documentation on the where tutorial. My only gotcha here is that the numeric examples make it hard to add new examples in between. I'm not sure renaming all the tutorials is the best approach. This is a very similar problem as creating taxonomies in design systems, this is why people name things in hundreds (100, 200, 300...), so if a new thing needs to be added in between it can be added without having to rename things afterwards. In my case, I've just added a 5 after the 6 to denote "this tutorial goes between the 6th and the 7th".

I hope this is useful!
