vscode-jupyter: `shift + enter` broken again

Issue Type: Bug

reference: https://github.com/microsoft/vscode-python/issues/3397 https://github.com/microsoft/vscode-python/issues/5621

Below is my current keyboard shortcuts json, which was working just fine prior to the most recent vscode update.

Before, when:

1. the editor had focus,
2. no text was selected in the editor,
3. in a file with #%% code ‘cell’ markers,

the entire ‘cell’ would run in the Python Interactive Pane and the focus would advance to the next ‘cell’ in the editor.

Now after the most recent vscode update and given the same conditions, only the line that the cursor is currently on is run in the Python Interactive Pane.

[
    {
        "key": "ctrl+shift+alt+enter",
        "command": "python.execSelectionInTerminal",
        "when": "editorFocus && !findInputFocussed && !python.datascience.ownsSelection && !replaceInputFocussed && editorLangId == 'python'"
    },
    {
        "key": "shift+enter",
        "command": "-python.execSelectionInTerminal",
        "when": "editorFocus && !findInputFocussed && !python.datascience.ownsSelection && !replaceInputFocussed && editorLangId == 'python'"
    },
    {
        "key": "shift+enter",
        "command": "python.datascience.execSelectionInteractive",
        "when": "editorFocus && !python.datascience.hascodecells && !findInputFocussed && !python.datascience.ownsSelection && !replaceInputFocussed && editorLangId == 'python'"
    },
    {
        "key": "shift+enter",
        "command": "python.datascience.execSelectionInteractive",
        "when": "editorFocus && python.datascience.hascodecells && !findInputFocussed && !python.datascience.ownsSelection && !replaceInputFocussed && editorLangId == 'python'"
    },
    {
        "key": "shift+enter",
        "command": "python.datascience.execSelectionInteractive",
        "when": "editorFocus && python.datascience.featureenabled && python.datascience.ownsSelection && !findInputFocussed && !replaceInputFocussed && editorLangId == 'python'"
    },
    {
        "key": "shift+enter",
        "command": "python.datascience.runcurrentcelladvance",
        "when": "editorFocus && python.datascience.featureenabled && python.datascience.hascodecells && !editorHasSelection && editorLangId == 'python'"
    }
