These 2 files are the same except for line 50 and 51. How could I do this with a filter instead of using the modified page.php in my child theme. It seems inefficient to use so much code to essentially change 2 lines.

modified page.php

<?php

    // calling the header.php
    get_header();

    // action hook for placing content above #container
    thematic_abovecontainer();

?>

            <?php
        
            // calling the widget area 'page-top'
            get_sidebar('page-top');

            the_post();
