Hello Team,
@mattetti @chanezon @arschles @saragibby

I have made some changes by adding the git log command.

Looking forward to hearing from you.

This is a good idea to add into the GitHub lesson, as git log is a handy command to know. To keep the first task simple to introduce git commands it would be better to move this to the follow on task for "Task: Merge some code". Utilizing git log within that task would be helpful to demostate how git log can be used.

Closing this PR in favor of issue #1108 that covers the addition of git log to the 2-github-basics lesson.
