checking git on godspeed create

[sakshiarora386]

The Problem :

When running the godspeed create command without having git installed, the following error message is displayed:
"git command not found"

Proposed Solution:
Check for Git Installation:
Before executing any git-related operations, verify if git is installed on the system.

1. If installed, fix your path variable in current environment, or close this shell and open a new one.
2. If not installed, Give message to user - “git command not found. Make sure git is installed on your system."
