Shift+O behavior to toggle whether long output is full displayed or made scrollable is missing

[greazer]

Testing #131209

• Run a cell that contains something like:

for i in range(0,1000): 
    print(i)

By default VS Code will show 30 lines and provide a link to view the entire output. In Jupyter, the expectation would be that pressing Shift+O would allow you to see the entire output inline within the notebook. It will toggle back to truncated (or scrollable in the case of Jupyter) on pressing Shift+O again.

Note that this issue is highly related to microsoft/vscode-jupyter#7096

Closing as dupe of #144111, since that one was entered by a non-biased user. :)
