A way to add all Edge colorschemes to Alacritty and select one

Hi there - thanks for the awesome Edge colorscheme. I've been using it quite happily since shortly after you first posted it on GH.

I've been experimenting with Alacritty for the past 2 days, and was thrilled to discover you've already created Edge schemes for it. In your README, you provide 4 separate schemes, and advise users to choose one and paste into their config.

Alacritty does support multiple themes, so as a slight optimization, if you wanted you could present a single pastable block containing all 4 schemes, and then advise users how they can easily switch between them. As an added bonus, if the Alacritty setting live_config_reload: true is active, then they can switch between color schemes with a one-line change, save the file, and see live previews.

The following is the self-documenting configuration I'm using with my Alacritty:

### Define your various colour-schemes here, and then choose one with
