[BUG] The 'circuitpython' repository has n submodules which won't be opened automatically.

[muranyia]

Describe the bug As far as I understand, not all circuitpython submodules are updated.

To Reproduce Steps to reproduce the behavior:

1. Install extension
2. Auto update says: "The 'circuitpython' repository has n submodules which won't be opened automatically. You can still open each one individually by opening a file within."

Expected behavior All submodules are updated.

Desktop (please complete the following information):

• OS: Linux
• Version Ubuntu 20.04.4 LTS

Additional context Circuitpython submodules cannot be updated by git pull --recurse-submodules, instead make fetch-submodules must be used.
