Since this is under the chocolatey-community user, it probably should not be using the icon for official products? Similar to chocolatey-community/chocolatey-templates#11 a new icon would probably need to be created.

🤔 for some reason I thought I had taken this icon from the Chocolatey Community Validation Extension, but it looks like it's not using an icon either. Perhaps this one should leave the extension off for now.

Setting this back to Draft because apparently the publish step isn't picking up that it's a Pull Request, which means that it is not ready for merging until I can spend some time tracking that down 🤷‍♂️. It also means that all pushes to it will fail to build on Team City until I get that sorted out.
