Fix jQuery not found error when jquery is loaded with defer

Description of the Change

Changelog Entry

Fixed - Bug fix

When loading jQuery with defer. jQuery will not be found. WordPress supports this natively now, but just does not apply it by default to jQuery.

I have seen other occurrences in the plugin ZeroSpamDavidWalsh() being added with and without a DOMContentLoaded wrapper. So they probably should all be changed to use the wrapper, but I am doing this PR just for this for now. Actually it might only he one in the WooCommerce class.

Also:

1. WP coding standards applied.
2. Based on the comment, this is actually just for "wpDiscuz plugin" so it does not need to be loaded at all for most users. Ideally, there should be a check if that plugin is active.
3. Is jQuery still needed on the frontend? Would love to see it gone. It's 2024 I consider it to outdated bloat.
