Setting Up Git: Remove sentence under Step 2.5

[Selethenn]

Because

The Foundations lesson, Setting up git, has a reference to GitHub directions for testing your SSH connection. Step 2.5 Testing your key included a line stating, "(Don't forget to omit the $ when you copy and paste the code!)". This is no longer applicable as the GitHub testing code no longer include a $. The code is now:

ssh -T [email protected]
# Attempts to ssh to GitHub
