"Also Available In" Links Above Polylang Posts
Shows a short line above each post or page listing the other languages it has been translated into, with links, so visitors who arrive in the wrong language can switch straight away.

$wpide_label = 'Also available in:'; // Text before the links.
add_filter( 'the_content', function ( $content ) use ( $wpide_label ) {
