[vscode] Notebook CodeActionKind Support

[rschnekenbu]

What it does

Fix missing API CodeActionKind notebook made public on vscode 1.83.
The static kind is available for notebooks, which allows to activate an extension without troubles and to register notebook edit values.
As a remark, the preferences do not align on the current vscode versions for 'editor: Code Actions On Save' possible values. There are no more boolean, but enum (automatic / explicit / etc.).
As a second remark, the save Participant behavior is not yet supported, and the adaptations required for notebook saveParticipants are not yet available. So all adaptations made on vscode issue 192248 cannot be implemented.

Fixes #13059

How to test

1. Install the following extension on Theia master:

2. Start browser theia

3. On activation, the following error is shown:
   

4. Switch to the branch and rebuild

5. Starting with the extension, no more errors shall popup

6. an action item shall come when in the cell of a notebook editor. I created a 'test.ipynb' file for that with dummy content. The action will add content to the cell when selected.

Follow-ups

• Implement properly the saveParticipants and check the specific behavior for notebooks works as expected. see vscode issue for that.
• The preference 'editor:Code Actions On Save' shall be updated as soon as the monaco version is uplifted
