Uncaught ReferenceError: jQuery is not defined

Hi,

First of all big thanks for your wonderful anti-spam solution, which I use on multiple projects.

I’ve seen your plugin change log and noticed that you already done some fixes regarding to WordPress 5.6 jQuery update.

However I’m still facing that problem – “Uncaught ReferenceError: jQuery is not defined”, which refers to inline jQuery code from the plugin:

jQuery( document ).ready( function ( $ ) {
				var gforms = '.gform_wrapper form';
				$( document ).on( 'submit', gforms, function () {
					$( '<input>' ).attr( 'type', 'hidden' )
						.attr( 'name', 'gf_zero_spam_key' )
						.attr( 'value', '#' )
						.appendTo( gforms );

					return true;
				} );
			} );

Would you have any suggestions on fix?
