hooks/EXAMPLES/SA-??? - test with git-secrets, git-hound, and truffleHog

[BradleyA]

Need to test with git-secrets (Prevents you from committing passwords and other sensitive information to a Git repository), should work git-hound (Git plugin that prevents sensitive data from being committed.) truffleHog (Searches through git repositories for high entropy strings and secrets, digging deep into commit history)

Update README on how the test worked and add knowledge about how to add these pre-commit commands (git-secrets, git-hound, and truffleHog) before unwanted information is committed to the local and remote Git repository.
