Restore notebooks after reload

[jrieken]

There is this

vscode/src/vs/workbench/contrib/notebook/browser/notebook.contribution.ts

Lines 79 to 82 in d1354bb

	// TODO@joh,peng this is disabled because the note-editor isn't fit for being
	// restorted (as it seems)
	if ('true') {
	return undefined;

In theory it should enable notebooks to be restored after reload but often the webview doesn't make it...

@rebornix I have pushed a change to restore notebook inputs after reload. This works OK but the webview isn't happy when reloading 2 or more notebooks after start...

I think the issue you see is a duplicate of #92128 , let's track it there.

[rebornix]

If I have two editor groups opening the same notebook, after reloading the window, one of the editor group never finished opening. Will investigate.

Fixed.
