[Authentication] Update image of ListObject from PasswordSheet to match code

[Mo-Gul]

In the second image of your great article https://rubberduckvba.wordpress.com/2020/02/06/password-authentication/

the header of the last column is Hash, but in the code PasswordHash is used. I guess updating the image is better than updating the code. Here is an image which you could use.

If you prefer updating the code let me know and I'll file a PR.
