Hey folks, after installing the most recent release I'm seeing the following error when attempting to list extensions:

KeyError: 'packageManager'  not found inside install.json

Looks to be related to the changes in #5096, and potentially mixing of source extensions with federated ones?

I also have this issue with jupyterlab==4.2.5. For me, it appears to be happening on all 6.1.x versions. Dropping to 6.0.1 resolved the issue.

The contents of my jupyter/labextensions/jupyterlab-plotly/install.json when I have 6.1.2 installed (note the incorrect version also).

{
    "schemaVersion": 1,
    "name": "jupyterlab-plotly",
    "version": "6.0.1",
    "jupyterlab": {
      "mimeExtension": "lib/mimeExtension.js"
    }
}

Oddly enough this file is missing when 6.0.1 is installed.
