Feature: (sort-switch-case) Would you consider sorting the `case` blocks in a `switch` statement?

[u3u]

Describe the rule

Can you add a sort-switch-case rule? It will sort the case statements, their order does not affect the execution result, but it can improve readability, reduce code merge conflicts, and eliminate the need to worry about their order when writing code.

Code example

Input

switch (type) {
  case 'save': {
    break;
  }

  case 'edit': {
    break;
  }

  default:
  case 'close': {
    break;
  }
}

Output

switch (type) {
  default:
  case 'close': {
    break;
  }

  case 'edit': {
    break;
  }

  case 'save': {
    break;
  }
}

That's a cool idea. I think we should add that.

The form switch(true) will become more popular with the release of typescript 5.3 https://www.typescriptlang.org/docs/handbook/release-notes/typescript-5-3.html#switch-true-narrowing

That also makes this feature more difficult to implement if switching the order of cases causes type errors, but maybe that is just revealing a bug

@Pyrolistical Yes, thank you for the comment. Safety is our priority.

@azat-io Hi, thank you for implementing this!! but it seems that it cannot be used together with unicorn/switch-case-braces. And there is a slight issue with sorting when case and default are used together.
