Update group-title.md
Update group-title.md

Minor changes. Note that client side (or server side) is only hyphenated when you use it as an adjective. So look at these two examples:

Ex 1: Use this script to change the titles on the client side, or just manually change it.
Ex 2: You can use a client-side script to change the titles.

Feel free to pass that on to the team if you keep a document of things like this (when I worked there I had a list of terms - frankly you might just want to have one in GitHub for all of the teams to share so others can contribute to it).
