worksheet.add_protected_range() - impossible to create the warning_only=True range

[aperepel]

Hi, I wonder if there's a bug.

When using worksheet.add_protected_range(name="A1:B2", warning_only=True), I'm getting the TypeError: Worksheet.add_protected_range() missing 1 required positional argument: 'editor_users_emails'

However, adding editor_users_emails triggers a 400 Bad Request, as the library seems to always require it:

worksheet.add_protected_range(name="A1:B2", warning_only=True, editor_users_emails="me@example.com")

--- (and the error is)

ProtectedRange is warningOnly. Editors cannot be set on it.

I think the gspread library must omit the editor node altogether from the request if warning_only=True.

FYI, I had to fallback to the raw API, here's what the working request looks like:

grid_range = gspread_utils.a1_range_to_grid_range(cell_range)

    request_body = {
        "requests": [
          {
              "addProtectedRange": {
                  "protectedRange": {
                      "range": {
                          "sheetId": int(worksheet_id),
                          "startRowIndex": grid_range['startRowIndex'],
                          "endRowIndex": grid_range['endRowIndex'],
                          "startColumnIndex": grid_range['startColumnIndex'],
                          "endColumnIndex": grid_range['endColumnIndex'],
                      },
                      "warningOnly": True
                  }
              }
          }
       ]
    }

    res = gsheet.batch_update(request_body)

Hi, thanks for this issue. You have made it very clear the problem, which is great.

I have made a fix with #1439. If no problems arise, it should appear in the next minor release :)
