Recommend zustand for global state management

[MalcolmTomisin]

• Zustand has a similar API to Redux (Selectors etc)
• Way less boilerplate
• Growing popularity as Redux's gets limited to legacy codebases
• New projects get set up with new generation state managers (Tanstack-query, Valtio, MST, Zustand)
• Zustand is lighweight, lightweight is important for React Native
• Performant with transient updates that don't cause re-renders

Is the mobile team using Zustand a lot? I've never worked with it. I'd love to see how we're using it on our client work.

@pangolingo I don't think there has been opportunities to experience Zustand on client work. New projects are more likely to use zustand.
We are currently looking at writing a series of React Native and Rails blog posts. Zustand and Redux comparisons may feature in one of those posts.

I suggest that we convert this PR to a draft, and don't merge until until more thoughtbotters have enough first-hand experience to recommend Zustand over Redux.

Hi @pangolingo, yeah I like that suggestion. Ideally, we should get more experience with Zustand and adoption on client projects before changing the guide. @MalcolmTomisin I really liked the idea of writing a blog post about comparing both.
