Capitalize word "Hook" (#6424)

Summary of changes:
See <reactjs/react.dev#6417>.

There is one exception though. The error message
“Rendered fewer hooks than expected” from React is indeed "hooks"
so I kept as-is. Shall we change the error message from React?

 In the React 18 Working Group we worked with library maintainers to create new APIs needed to support concurrent rendering for use cases specific to their use case in areas like styles, and external stores. To support React 18, some libraries may need to switch to one of the following APIs:
 
-* `useSyncExternalStore` is a new hook that allows external stores to support concurrent reads by forcing updates to the store to be synchronous. This new API is recommended for any library that integrates with state external to React. For more information, see the [useSyncExternalStore overview post](https://github.com/reactwg/react-18/discussions/70) and [useSyncExternalStore API details](https://github.com/reactwg/react-18/discussions/86).
-* `useInsertionEffect` is a new hook that allows CSS-in-JS libraries to address performance issues of injecting styles in render. Unless you've already built a CSS-in-JS library we don't expect you to ever use this. This hook will run after the DOM is mutated, but before layout effects read the new layout. This solves an issue that already exists in React 17 and below, but is even more important in React 18 because React yields to the browser during concurrent rendering, giving it a chance to recalculate layout. For more information, see the [Library Upgrade Guide for `<style>`](https://github.com/reactwg/react-18/discussions/110).

 React 18 also introduces new APIs for concurrent rendering such as `startTransition`, `useDeferredValue` and `useId`, which we share more about in the [release post](/blog/2022/03/29/react-v18).

 Transitions will opt in to concurrent rendering, which allows the update to be interrupted. If the content re-suspends, transitions also tell React to continue showing the current content while rendering the transition content in the background (see the [Suspense RFC](https://github.com/reactjs/rfcs/blob/main/text/0213-suspense-in-react-18.md) for more info).

 We gave an [early preview](https://www.youtube.com/watch?v=lGEMwh32soc) of React Forget at React Conf 2021. It’s a compiler that automatically generates the equivalent of `useMemo` and `useCallback` calls to minimize the cost of re-rendering, while retaining React’s programming model.
 
-Recently, we finished a rewrite of the compiler to make it more reliable and capable. This new architecture allows us to analyze and memoize more complex patterns such as the use of [local mutations](/learn/keeping-components-pure#local-mutation-your-components-little-secret), and opens up many new compile-time optimization opportunities beyond just being on par with memoization hooks.

 We’re also working on a playground for exploring many aspects of the compiler. While the goal of the playground is to make development of the compiler easier, we think that it will make it easier to try it out and build intuition for what the compiler does. It reveals various insights into how it works under the hood, and live renders the compiler’s outputs as you type. This will be shipped together with the compiler when it’s released.

 Since our last update, we have merged the [React Server Components RFC](https://github.com/reactjs/rfcs/blob/main/text/0188-server-components.md) to ratify the proposal. We resolved outstanding issues with the [React Server Module Conventions](https://github.com/reactjs/rfcs/blob/main/text/0227-server-module-conventions.md) proposal, and reached consensus with our partners to go with the `"use client"` convention. These documents also act as specification for what an RSC-compatible implementation should support.
 
-The biggest change is that we introduced [`async` / `await`](https://github.com/reactjs/rfcs/pull/229) as the primary way to do data fetching from Server Components. We also plan to support data loading from the client by introducing a new hook called `use` that unwraps Promises. Although we can't support `async / await` in arbitrary components in client-only apps, we plan to add support for it when you structure your client-only app similar to how RSC apps are structured.

 Now that we have data fetching pretty well sorted, we're exploring the other direction: sending data from the client to the server, so that you can execute database mutations and implement forms. We're doing this by letting you pass Server Action functions across the server/client boundary, which the client can then call, providing seamless RPC. Server Actions also give you progressively enhanced forms before JavaScript loads.
