PHP 8 incompatibility issue

We discovered an issue with your plugin that we would like to inform you about. Basically, the file modules/animated-gradient/module.php, on the line 127, calls the function implode on the $color variable, which is never initialized. If the variable is not filled by the previous loop, it will generate a TypeError, causing the page to stop executing (it thinks it is a string instead of the expected array).

We propose to initialize the variable $colors as an array on the line 121 (just before the loop).

We would like to know if you plan to address this soon. Thanks in advance.
