T01 Review Inconsistent Titles Capitalization

The titles in various slides have different capitalization.

Examples:

• Why use version control? (Slide 4) -> Why Use Version Control?
• Motivation for learning to use git (Slide 5) -> Motivation for Learning to Use Git
• Installing git (slide 6) -> Installing Git
• git status (slide 19) -> Git Status (although this is the command so maybe not?)
