Change "git add ." to "git add -A"

[zaidsidd360]

The dot after git add is a little harder to read and a lot of people have seemed to miss it. Replacing "git add ." with "git add -A"(which has the exact same functionality as the former since git version 2.0) will make it more readable for beginners.
