Support for XState v5 `guard` transition property

[ts-candide]

Describe the bug

XState v5 has renamed the cond property to guard for guarded transitions. This plugin reports guard as an invalid transition property when placed inside an invoke.onDone array.

Expected behavior

No error when using guard as a transition property inside an invoke.onDone array.

Actual behavior

An ESLint error is shown when using guard as a transition property inside an invoke.onDone array.

Versions (please complete the following information):

• Node version: 20.9.0
• ESLint version: 8.55.0
• eslint-plugin-xstate version: 1.1.3
• xstate version: 5.1.0

Additional context

Here is some sample machine config:

{
  states: {
    selectingReader: {
      invoke: {
        src: "startDiscoveringReaders",
        onDone: [
          {
            guard: "noReadersDiscovered",
            target: "noReadersFound",
          },
        ],
        onError: "errored",
      },
    }
  }
}

The guard property is being marked as invalid here.

@ts-candide The version you are using is not compatible with xstate v5. Please use eslint-plugin-xstate@next.

Version 3.2.1 of this plugin now supports xstate v5.
