Publish VS Code Plugin on OpenVSX

[andreapiso]

As per title. Right now the plugin is only published on the proprietary VS Code marketplace. Would it be possible to publish it on OpenVSX too? Then VSCode derived editors like Theia would be able to use it.

Here are the publishing instructions. It comes down to adding ovsx publish command in addition to your normal vsce publish IIRC.

Let me explain why this is needed: packages such as code or vscodium can't use Visual Studio Marketplace due to the fact that their Terms of Use restricts it only to Microsoft's products, so Open VSX registry is offered as an alternative.

Thanks for making this extension!
