function media_library_post_update_update_8001_checkbox_classes in Drupal 8

Add non js prefixed classes to checkboxes if not present.

Note the inclusion of "update_8001" in the function name. This ensures the function is executed after media_library_post_update_table_display(), as hook_post_update_NAME() implementations within the same file are executed in alphanumeric order.
