Thanks for letting us know about this issue! It has now been fixed on the Store Page. You should be able to download the entire (itch) Plugin Suite as a zip folder.
You can find all the plugins in the suite in the Demo Projects. We usually have a separate zip folder for just the Plugins, but it seems last update only the main plugin was uploaded. This is on us, we apologize for any inconvenience caused. Let us know if there are any other issues we can help you with.
