fix(docs): list the contributing guide where it actually lives

[hyperpolymath]

The "Repository Structure" block still listed CONTRIBUTING.md at the repository root, but the guide lives at .github/CONTRIBUTING.md — the entry pointed at a location it had already moved away from.

This is the only change: the entry moves under the tree's existing .github/ branch, at the block's own comment column. The tree already rendered correctly and its layout is untouched.

_{A rabbit checks the tidy tree
CONTRIBUTING rests where it should be
The .github/ path is clear
Its file annotation stays near
One small move, and order grows
The repository neatly shows}
