Program Security - Updated duplicate mutable accounts lesson #399

changed the title
| Consider a program that updates a data field for `user_a` and `user_b` in a | ||
| single instruction. If the same account is passed for both `user_a` and | ||
| `user_b`, the program will overwrite the data field with the second value, | ||
| potentially leading to unintended side effects. |

Excellent @0xCipherCoder - this has a lot higher signal:noise ratio than the older version.
