Arrow function with expression body results function size error

[zymbth]

Describe the bug
Arrow function with expression body results the error calculation of function rows.

To Reproduce
Steps to reproduce the behavior:

1. What is the exact code you are analyzing?

const sum = (a, b) => a + b

const someVal = 100

function func() {
  // ...
  // ...
  // ...
  // ...
  // ...
  // ...
  // ...
  // ...
  // ...
  // ...
  // ...
  // ...
  // ...
  // ...
  // ...
  // ...
  // ...
  // ...
}

2. What is the output you are getting?

-  rrd ~ function size
   src\views\Test\test.js
   👉 Functions must be shorter than 20 lines. See: https://vue-mess-detector.webmania.cc/rules/rrd/function-size.html
   function (sum#1) is too long: 24 lines 🚨

Expected behavior
Arrow function with expression body should be calculated correctly.

I'm working on a refactor of the functionSize rule using babel parser to handle better and avoid this common false positives or edge-cases. I just removed the .todo from the test added in this issue and it works 🫡

Soon you will be able to try it out and that code health will be 100% 🙌
