Fatal error with WordPress 6.5+

Hi there!

First of all, thanks for creating this plugin! I use it a lot to debug translation issues.

For some time now, the following error has started to happen. It seems related to WP 6.5+:

Fatal error: Uncaught Error: Call to undefined method WP_Translations::get_header() in /Users/diegopereira/Local Sites/compsupp-7554/app/public/wp-content/plugins/debug-bar-localization/class-debug-bar-localization.php:463 Stack trace: #0 /Users/diegopereira/Local Sites/compsupp-7554/app/public/wp-content/plugins/debug-bar-localization/class-debug-bar-localization.php(385): Debug_Bar_Localization->render_last_updated('default') #1 /Users/diegopereira/Local Sites/compsupp-7554/app/public/wp-content/plugins/debug-bar-localization/class-debug-bar-localization.php(331): Debug_Bar_Localization->render_load_textdomain_table('core') #2 /Users/diegopereira/Local Sites/compsupp-7554/app/public/wp-content/plugins/debug-bar-localization/class-debug-bar-localization.php(181): Debug_Bar_Localization->render_load_textdomain_section() #3 /Users/diegopereira/Local Sites/compsupp-7554/app/public/wp-content/plugins/debug-bar/debug-bar.php(377): Debug_Bar_Localization->render() #4 /Users/diegopereira/Local Sites/compsupp-7554/app/public/wp- in /Users/diegopereira/Local Sites/compsupp-7554/app/public/wp-content/plugins/debug-bar-localization/class-debug-bar-localization.php on line 463

It could be fixed by replacing Debug_Bar_Localization::render_last_updated() with:

protected function render_last_updated( $domain ) {
	// Verifica se o domínio de tradução está carregado
	if ( ! isset( $GLOBALS['l10n'][ $domain ] ) ) {
		echo '-';
		return;
	}

	// Recupera as traduções para o domínio específico
	$translations = $GLOBALS['l10n'][ $domain ];

	// Inicializa as variáveis para X-Generator e PO-Revision-Date
	$x_generator = false;
	$revision_date = false;

	// Verifica se os cabeçalhos estão definidos
	if ( isset( $translations->headers['X-Generator'] ) ) {
		$x_generator = $translations->headers['X-Generator'];
	}

	if ( isset( $translations->headers['PO-Revision-Date'] ) ) {
		$revision_date = $translations->headers['PO-Revision-Date'];
	}

	if ( false === $revision_date ) {
		echo '-';
		return;
	}

	$generator = __( 'unknown', 'debug-bar-localization' );
	if ( ! empty( $x_generator ) && is_string( $x_generator ) ) {
		if ( false !== strpos( $x_generator, 'GlotPress' ) ) {
			$generator = 'GlotPress';
		} elseif ( false !== strpos( $x_generator, 'Poedit' ) ) {
			$generator = 'Poedit';
		} else {
			$generator = $x_generator;
		}
	}

	echo wp_kses_post( sprintf(
		/* translators: 1: date, 2: translation program name. */
		__( '%s via %s', 'debug-bar-localization' ),
		substr( $revision_date, 0, 10 ),
		'<em>' . $generator . '</em>'
	) );
}
