Controllers: Rails 8 docs conflicts with the current lesson (based on Rails 7)

Describe your suggestion

My concerns are:

1. To explicitly allow parameters, the lesson suggests to use require with permit. However, I'm following the version 8 docs, but it strongly recommends to use expect, which "requires" and "permits" parameters all at once. The logic and syntax is understandable, but it kinda confused me which one should I use as I move forward in the curriculum, and even considered to downgrade the Rails version.
2. While this one is not originally an issue for me, I think it's also worth mentioning that the TOP lesson and docs exposes us about flash messages. The generated models and controllers in the project use a different syntax for the flash like so:
   format.html { redirect_to @car, notice: "Car was successfully updated." }, unlike the lesson's introduction to flash messages.

This clearly led to a confusion. I suggest that the lesson must expose us for what's to come when following the Rails 8 docs, as well as what Rails generates in the project (since I also explore the project at the same time). This way, we'll be prepared for content, we'll know which is better/suited for certain cases, and minimise confusion for different Rails versions.

Thank you for making this issue @Monatric

I'm only going to address the stuff with strong parameters in my PR as that's already a solid chunk of work to consider and review. If you have strong feelings about the flash message stuff, I recommend opening a different issue for that so it can be tackled separately.
