PHP Warning: Undefined array key "cpel_lv_languages"

Issue:

Rest of the PHP warning:
PHP Warning: Undefined array key "cpel_lv_languages" in /plugins/connect-polylang-elementor/includes/language-visibility.php on line 134

This kicks out in the php log with custom Elementor widgets when saving a post in the elementor editor

Looks like my PHP 8.2 doesn't like that $languages doesn't have a fallback value like an empty array when instantiated, when $settings['cpel_lv_languages'] is null/empty.

Currently
$languages = (array) $settings['cpel_lv_languages'];

Solution:

Both of these lines below worked for me to solve the issue by replacing line #134:

Option 1)
Matches best with current plugin PHP code principles:
$languages = isset( $settings['cpel_lv_languages'] ) ? $settings['cpel_lv_languages'] : array();

Option 2)
PHP 7+ compatible null coalescing operator and array shorthand:
$languages = isset( $settings['cpel_lv_languages'] ) ?? [];

Plugin Versions:

Connect Polylang for Elementor: 2.4.3
Elementor 3.20.0
Elementor Pro 3.18.2
Polylang Pro 3.5.2

Thanks for the report. The fix will be included in the next version.
