consider to pack as vsix and publish as GitHub releases

[akosyakov]

There are 2 gotchas:

• VS Code team does not package these extensions, so it could be impossible because of missing attributes or files
• pulling from GitHub require GitHub token compare to npm

@akosyakov you mention potential downsides, but what would be the main advantage(s) to distribute these built-in extensions as vsix file(s) vs NPM packages?

[akosyakov]

There are probably could be 2:

• less magic in the plugin system, if you can just consume vsix
• the same packaging as non built-in extensions

Another reason to do it: eclipse-theia/theia#6207

We go with publishing to Open VSX Registry instead.
