Publish extensions to open-vsx

[orblazer]

I'm a VS Codium user, a FLOSS version of VS Code, it's the same code but without the Microsoft's telemetry and branding. I want to request if possible to add the CSS Peek extension on the open-vsx.org market to us doesn't need to works with the Microsoft marketplace as is unclear if it's legal to use it on VS Code forks, see here.

Additional info:

• This is how to publish a new extension.
