tour: Confusing comment in the console on tour/basics/16

Context: https://go.dev/tour/basics/16

```
// Create a huge number by shifting a 1 bit left 100 places.
// In other words, the binary number that is 1 followed by 100 zeroes.
```

this comment is very confusing, instead it should be 
```
// Create a huge number by shifting a 1 bit left 100 places.
// In other words, the binary number that is 1 multiplied by 2, hundred times.
```
