Update docs for slice pattern and usage of middleware such as devtools example included

[enyelsequeira]

I was talking with @dai-shi about this and maybe this should be an issue to update

ideally it would be great to have a bit better documentation about the different slices patterns and how they can work or be used in different stores, example like this below

const useStore = create<
  UserSlice & UserActionSlice & TokensSlice & PasscodeAndEmailSetupSlice
>()((...a) => ({
  ...CreateUserSlice(...a),
  ...UserActions(...a),
  ...PassCodeAndEmail(...a),
  ...TokenValues(...a),
}));

How can I update the store from another one if I am using the slices patterns
and yes, we have an example of how they work, but I think maybe there should be an depth documentation to better help other developers

Cheers,

@chrisk-7777 any thoughts on this?

[chrisk-7777]

100% agree. I feel like we also had this in the wiki at some point.

I've added the documentation label and believe it should stay open.
