Publish extensions to open-vsx

I'm a [VS Codium](https://github.com/VSCodium/vscodium) 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 _Apollo GraphQL_ extension on the [open-vsx.org](https://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](https://github.com/microsoft/vscode/issues/31168).

Additional info:

- This is [how to](https://github.com/eclipse/openvsx/wiki/Publishing-Extensions) publish a new extension.

Start with the Open VSX publishing guide linked in the issue and locate the Apollo GraphQL extension package in this repository. Confirm the package metadata and publishing requirements, then verify that the extension is available on open-vsx.org for VS Codium users.
