no-async-in-computed-properties fails on objects containing async functions

[cjpearson]

This can be seen on the demo page for the rule here. Adding the following computed property causes an ESLint error.

test () {
  return {
    callback: async (e) => e
  }
}

What did you expect to happen?
No error since computing the result of the computed property is not asynchronous.

What actually happened?
There is an error on the property.
