[Icon request] Shadow Alpha and Beta

[NicolasGuilloux]

Thanks for this awesome icon pack. I love it and I'm using it for years now.
For the first time, I would like to request 2 new icons and few changes.

• App Name: Shadow Beta and Alpha
• Icon Name: shadow-preprod.svg, shadow-testing.svg
• Description: Right now, there already is an icon for Shadow which is great but is not named well. The official Shadow icon should be named shadow.svg. Moreover, as this is still a cutting edge technology, the users often has to switch between environments such as Beta or Alpha. The Beta icon should be named shadow-preprod.svg and the Alpha icon shadow-testing.svg.
• Webpage (optional): https://shadow.tech
• Original Icon:

It's right?

• shadow > appimagekit-shadow (Stable)
• shadow-dev > shadow-testing appimagekit-shadow-dev appimagekit-shadow-testing(Alpha label)
• shadow-beta > shadow-preprod appimagekit-shadow-beta appimagekit-shadow-preprod (Beta label)
  Also application provide appimage... I hope not confused with that
