Automatically add `mutationKey` to mutations

[piedrahitapablo]

First of all thanks for developing this awesome library, it has been a joy to work with it. I found a possible way to improve it but I'm not sure if you already considered the option.

Today I was trying to use TanStack Query's useIsMutating like this:

const count = useIsMutating({
  mutationKey: apiHooks.getKeyByAlias('updateCart', {
    params: { id: cartId },
  }),
});

but it was always returning 0, I had to do some digging to realize that I needed to explicitly pass the mutationKey option to the useUpdateCart hook:

apiHooks.useUpdateCart(
  { params: { id: cartId } },
  { 
    mutationKey: apiHooks.getKeyByAlias('updateCart', {
      params: { id: cartId },
    })
  }
)

So I think it will be good to add the mutationKey automatically, let me know if it makes sense and I can create a PR for it.
