feat: format for named tuple

[xuzuodong]

Description

Vue 3.3 provides a new way to define props, which leverages named tuples:

const emit = defineEmits<{
  change: [id: number]
  update: [value: string]
}>()

However, I didn't find a ESLint rule that checks spaces between colon in named tuples. It would be nice to have one.

// good
type T = [i: number]

const emit = defineEmits<{
    change: [id: number]
    update: [value: string]
}>()

// bad
type T = [i:number]
type T = [i : number]

const emit = defineEmits<{
    change: [id:number]
    update: [value:string]
}>()
