Add timing to your plant control server navigation doesnt work

[emfoster11]

Link for "Add timing to your plant control" in README.md in "Automated plant watering" does not navigate like rest of the links.

Add timing to your plant control does not point to text "Add timing to your plant control server" appropriately and link doesn't navigate. I used these links when navigating around the lessons. Current link - Add timing to your plant control

Good spot @emfoster11. Should be fixed now.
