Add extension to OpenVSX

[bennihtm]

Is it possible to add the Extension to the OpenVSX Store?

The OpenVSX store is an alternative to the proprietary and vendor-dependend store backend used by Microsoft.
VSCodium - an fully open source distribution of Visual Studio Code uses OpenVSX as a replacement to the Microsoft Store.

The guide on how to add extensions can be found here: https://github.com/eclipse/openvsx/wiki/Publishing-Extensions
