Rule Proposal: single object in class array

[privatenumber]

Please describe what the rule should do:

The rule should enforce that only one object is used in an array of classes

What category should the rule belong to?

• Enforces code style
• Warns about a potential error
• Suggests an alternate way of doing something
• Other (please specify:)

Provide 2-3 code examples that this rule should warn about:

<template>
	<div :class="[{ a: true }, { b: true }, 'c']" />
</template>

Can be fixed to:

<template>
	<div :class="[{ a: true, b: true }, 'c']" />
</template>

Can open a PR if proposal is approved.
