Docs: Remove references to wrapped reducer function

[brandonroberts]

Other information:

In the docs we have reducers wrapped in an exported function

const _counterReducer = createReducer(
  initialState,
  on(increment, (state) => state + 1),
  on(decrement, (state) => state - 1),
  on(reset, (state) => 0)
);
 
export function counterReducer(state, action) {
  return _counterReducer(state, action);
}

This is not required with Ivy, which is the default now. Change these reducers to be directly exported

export const counterReducer = createReducer(
  initialState,
  on(increment, (state) => state + 1),
  on(decrement, (state) => state - 1),
  on(reset, (state) => 0)
);

I would be willing to submit a PR for the docs ❤️

Search for "createReducer" in /projects/ngrx.io directory and remove all reducer wrappers:

-const _reducer = createReducer(
+export const reducer = createReducer(
  initialState,
  on(a1, (state) => state + 1)
);
-
-export function reducer(state: State | undefined, action: Action) {
-  return _reducer(state, action);
-}

I have raised a PR. #3200 . In the description you have particularly mentioned docs, so I have made changes just in the .md files, but fyi, projects\ngrx.io\content\examples\store\src\app\counter.reducer.ts also contains a reducer wrapper
