[BREAKING] Get rid of .queue(), .getQueueStep(), .insertQueueStep(), . deleteQueueStep()

Current behavior

The .queue() method was introduced a log time ago in https://github.com/sweetalert2/sweetalert2/pull/165

In v11 the IE11 support will be dropped and all modern browsers support async/await: https://caniuse.com/?search=await

async/await can perfectly replace all use-cases of .queue() and therefore there’s no need in that old burden anymore.

for anyone else looking for an answer to this question this works:

  let q = ['a','b','c'];
  for (let i = 0; i < q.length; i++) {
      await Swal.fire(q[i]);
   }

The docs [1] show these options - these are no longer available?

progressSteps [] Progress steps, useful for queues.

currentProgressStep undefined Current active progress step.

progressStepsDistance undefined

EDIT: I see one referenced just recently: https://github.com/sweetalert2/sweetalert2/pull/2437 So how should these be used?
