Kirby 4 Support

[HYR]

This plugin is my new favorite plugin. Frankly, I feel like it should be part of the core but I'll settle for compatible with Kirby 4.x.

Any chance you'd have time to make compatible? My test shows when installed the v4 panel is just blank. Disabling the plugin, allows the panel to be seen.

@rasteiner Ping! Still hoping this can be made compatible with Kirby 4. Thanks again for your work on this plugin. :)
