Add extension to open-vsx

[cavcrosby]

In addition to having this extension published to the VS Code Marketplace, would the maintainer(s) be able to publish the extension to open-vsx?

For reference, open-vsx (and by extension open-vsx.org) is an open source alternative to the VS Code Marketplace (see source-repo https://github.com/eclipse/openvsx). This mainly helps in when not using pre-built binary of vscode (that is, you build it yourself or use https://github.com/VSCodium/vscodium), as using a self-built version may not (this is a gray area) be able to use the VS Code Marketplace for extensions. I'd like to see this gap close between building vscode yourself and using a pre-built binary.

To publish an extension to open-vsx, just follow this guide: https://github.com/eclipse/openvsx/wiki/Publishing-Extensions
If this is not possible, then its no problem, just let me know.
