refactor(rome_js_analyze): relax noConfusingArrow

[Conaclos]

Summary

I often encounter the warnings of noConfusingArrow and I am starting to disable it.
The rule looks too pedantic.

This PR relaxes noConfusingArrow by accepting all arrow functions that enclose its parameter with parenthesis.
Thus, the following snippet no longer triggers the rule:

var x = (a) => 1 ? 2 : 3;

The following snippet still triggers the rule:

var x = a => 1 ? 2 : 3;

This means that code formatted by Rome can no longer trigger this rule.
Another solution could be to remove the rule.

Test Plan

Tests updated.

Changelog

• The PR requires a changelog line

Documentation
