Adding zustand-boilerplate to third-party-libraries (#2673)

* Adding zustand-boilerplate to third-party-libraries

Hi, 
I'm the maker of zustand-boilerplate. It's a small utility that generates getters, setters based on a class representing a zustand store. I'd like to add it to the list of 3rd party libraries to let people know. I've attached an example:

```
import { create } from "zustand"
import * as Z from "zustand-boilerplate"

interface Bear {
  name: string
}

class BearStore {
  @Z.Boolean()
  isDangerous = false

  @Z.Number()
  count = 0

  @Z.Array()
  bears: Bear[] = []

  //
  // Notice you have to set a default value and apply the decorator
  // to properties for generated actions to work
  //
  @Z.Any()
  mainBear: Bear | undefined = undefined

  @Z.String()
  userName: string | undefined = undefined
}

const bearStoreWithActions = Z.generateStoreWithActions(BearStore)

export const store = create(bearStoreWithActions)

// The following will automatically work now (fully typed)
// store.getState().getBears() -> Bear[]
// store.getState().setBears(bears)
// ...
```

* chore: a-z ordering
