Upstream examples for queen-attack?

I’m still syncing the Rust track with problem-specifications.

I’ve noticed that the Rust track has additions to instructions.md of queen-attack.
They are not language-specific, so I’m thinking it should either be upstreamed or deleted.

What do you think?

### Examples of queens attacking:

```text
_ _ _ _ _ _ _ _     _ _ _ _ _ _ _ _     _ _ _ _ _ _ _ _
_ _ _ _ _ _ _ _     _ _ _ _ _ _ _ _     _ _ _ W _ _ _ _
_ _ _ W _ _ _ _     _ B _ _ _ W _ _     _ _ _ _ _ _ _ _
_ _ _ _ _ _ _ _     _ _ _ _ _ _ _ _     _ _ _ _ _ _ _ _
_ _ _ _ _ _ _ _     _ _ _ _ _ _ _ _     _ _ _ _ _ _ _ _
_ _ _ _ _ _ B _     _ _ _ _ _ _ _ _     _ _ _ _ _ _ _ _
_ _ _ _ _ _ _ _     _ _ _ _ _ _ _ _     _ _ _ B _ _ _ _
_ _ _ _ _ _ _ _     _ _ _ _ _ _ _ _     _ _ _ _ _ _ _ _
```

### Examples of queens not interacting:

```text
_ _ _ _ _ _ _ _     _ _ _ _ _ _ _ _     _ _ _ _ _ _ _ _
_ _ _ _ _ _ _ _     _ _ _ _ _ _ _ _     _ _ _ W _ _ _ _
_ _ _ _ _ _ _ _     _ _ _ _ _ W _ _     _ _ _ _ _ _ _ _
_ _ _ _ _ _ _ _     _ _ _ _ _ _ _ _     _ _ _ _ _ _ _ _
_ _ _ _ W _ _ _     _ _ _ _ _ _ _ _     _ _ _ _ _ _ _ _
_ _ _ _ _ _ B _     _ _ _ _ _ _ _ _     _ _ _ _ _ _ _ _
_ _ _ _ _ _ _ _     _ _ B _ _ _ _ _     _ _ _ _ _ _ B _
_ _ _ _ _ _ _ _     _ _ _ _ _ _ _ _     _ _ _ _ _ _ _ _
```

B and W stand for **Black** and **White**, the two sides competing against each other in a game of chess.
For this exercise you do not need to know which side the queens are on.

I like this - I’d like it more if we included images with this as the alt text :slight_smile:

Sounds cool! I’m not a graphic designer though, so I probably can’t help with that.

Paging @habere-et-dispertire, who did some really nice SVG artwork for this exercise. :smile:
