Feature: Add support for passing an array of strings or numbers to the containerId prop.

What is the current behavior?
Currently, we cannot show a toast in multiple containers without executing or calling the toast() function multiple times.

toast("hello Default", {
  autoClose: false,
  hideProgressBar: false,
  closeOnClick: true,
  pauseOnHover: true,
  draggable: true,
  progress: undefined,
  containerId: "gpt",
});

toast("hello Default", {
  autoClose: false,
  hideProgressBar: false,
  closeOnClick: true,
  pauseOnHover: true,
  draggable: true,
  progress: undefined,
  containerId: "default",
});

What is the expected behavior?
We expect that the toast function accepts a list of containerIds to show/attach to it.

toast("hello Default", {
  autoClose: false,
  hideProgressBar: false,
  closeOnClick: true,
  pauseOnHover: true,
  draggable: true,
  progress: undefined,
  containerId: ["default", "gpt"],
});
