Resolve Deprecated Parameter Order in facebook_comments.module

Issue Description:

The facebook_comments module in Drupal is encountering a deprecated warning on PHP 8.1 due to the order of parameters in a function declaration. Specifically, an optional parameter $mode is declared before a required parameter $amount in the module's facebook_comments.module file. This parameter order is causing the $mode parameter to be implicitly treated as a required parameter on PHP 8.1, resulting in the deprecated warning.

Steps to Reproduce:

  1. Enable the facebook_comments module in a Drupal instance.
  2. Access a page or content node with Facebook comments enabled.
  3. Observe the deprecated warning in the PHP error log or on the page while using PHP 8.1.

Expected Behavior:

The facebook_comments module should be PHP 8.1 compatible and not generate deprecated warnings. The module's function declarations should adhere to modern PHP practices without triggering deprecated behavior.

Proposed Solution:

To address the deprecated warning, it's recommended to make the $mode parameter mandatory by removing its default value in the relevant function declaration within the facebook_comments.module file. Since the value of $mode is consistently set whenever the function is called, the default value is unnecessary and contributes to the deprecated behavior.

Additional Information:

This issue affects the compatibility and reliability of the facebook_comments module on PHP 8.1. By adjusting the parameter order and removing the unnecessary default value, the module can function seamlessly on both older and newer PHP versions, providing a smooth experience for website administrators and users alike.
