Summary:
When bundling default plugins, we create a JSON-file containing information about the plugin and where to require it from. This information contained two filed: `entry` and `rootDir`, which were written while bundling the plugins. Because the plugins are bundled on Sandcastle, this was a path on the Sandcastle machine.
This also happened for the OSS version, see the screenshot from a GitHub issue.
Entry and rootDir are only used during the build process and not needed afterwards, so it is save to remove them from the JSON.
