i18n/multisite: Contextualize strings in theme update screen

[audrasjb]

In wp-admin/includes/class-wp-ms-themes-list-table.php file, under get_views function, only the first translatable screen is contextualized. Then, we have a gender issue in fr_FR with the other translatable strings. Thant would be nice to add a context to the other items as well.

switch ( $type ) {
        case 'all':
                $text = _nx( 'All <span class="count">(%s)</span>', 'All <span class="count">(%s)</span>', $count, 'themes' );
                break;
        case 'enabled':
                $text = _n( 'Enabled <span class="count">(%s)</span>', 'Enabled <span class="count">(%s)</span>', $count );
                break;
        case 'disabled':
                $text = _n( 'Disabled <span class="count">(%s)</span>', 'Disabled <span class="count">(%s)</span>', $count );
                break;
        case 'upgrade':
                $text = _n( 'Update Available <span class="count">(%s)</span>', 'Update Available <span class="count">(%s)</span>', $count );
                break;
        case 'broken':
                $text = _n( 'Broken <span class="count">(%s)</span>', 'Broken <span class="count">(%s)</span>', $count );
                break;
}
