 == Test Report

 === Env
 * WordPress: trunk (with [https://github.com/WordPress/wordpress-

 * Browser: Chrome v96.0.4664.110
 * OS: Windows 10 (WSL2)
 * Theme: Twenty Twenty-Two
 * Block Editor
 * Plugin: None activated

 === Steps to test
 1. Load `/wp-login.php`.
 2. The languages dropdown should be visible.
 3. Add the following to Twenty Twenty-Two's `functions.php` file and Save:
 {{{#!php
 add_filter( 'display_login_language_dropdown', '__return_false' );
 }}}
 4. Refresh `/wp-login.php`.
 5. The languages dropdown should no longer be visible.

 === Results
 - Before adding the filter, the languages dropdown was visible.
 - After adding the filter, the languages dropdown was no longer visible.
 - All works as expected. 👍
