Zipped release for manual install

[1ku1]

Is your feature request related to a problem? Please describe.

In order to install the plugin manually, you have to download the three files individually, then create a folder and rename it with the plugin id and put these files in it.

I know these files are needed for automatic installation to work, but it would be much easier for the user to be able to download a zipped file also from the releases tab in the following configuration:

plugin-id-{v}.zip
    plugin-id\
        main.js
        manifest.json
        styles.css

This way we can just extract the zip file in the plugin folder. Thank you.
