Bug Report

current behavior

the make-pot command seems to ignore javascript files using the optional chaining operator somewhere in the code completely.

reproduction

use the optional chaining operator in javascript files using the wp.i18n module like:

const {__} = wp.i18n;
..
..

const someReactComponent = () => (
 <>
   <a href={selectedPost?.link}>__('my translatable string')</a>
 </>
);
..
..

then use wp cli to generate a .pot file:

wp-cli wp i18n make-pot <plugin_dir> ./languages/.pot

expected outcome

the wp-cli i18n make-pot command includes javascript files using the optional chaining operator and successfully extracts the translation strings
