update readme examples

[alifeee]

closes #1410

The examples in the readme were wrong, and did not work

I think we should go through and test them to see if they work. I will do this soon if you do not. :)

The below example don't work either:

• gspread/README.md

  Line 264 in 2000540

  worksheet.update('B1', 'Bingo!')

  
  we should swap the value and the range too, and put the value into a matrix [[".."]]

apart from that the rest works fine 👍
