Amend https://theia-ide.org/docs/authoring_plugins tutorial

Hello,

https://theia-ide.org/docs/authoring_plugins tutorial does not mention that a few packages need be added to the running Theia instance package.json:

@theia/plugin-dev”: “next”,
@theia/plugin-ext”: “next”,
@theia/plugin-ext-vscode”: “next”

Without this the “Executing the Plug-in” section is not doable.

Thanks

Thanks for bringing the documentation issue to the projects attention @fcanteloup !
I’ve created an issue in the corresponding theia-website repo so it can be tracked. If you’d like, you can open a pull request to address the issue :slight_smile:
