[Theia AI] Diff editor line wrapping

[JonasHelming]

The diff editor does not use line wrapping on the left side, but uses line wrapping on the right hand side. This makes the diff editor hard to use for text documents. I did not see a setting to switch line wrapping for the diff editor. This applies for the change set diff editor, but also the regular triggered from the git view.

First observation: It looks like no matter what the values of the underlying preferences, the values read at this point in the Monaco editor are all off:

I believe our problem has to do with what's described here, since at the time that the code to create the widget runs, the div that will house it isn't attached, so we always run into the logic that sets wordWrapOverride2 to 'off'.
