Add pre-commit hook gitleaks to detect and prevent hardcoded secrets

https://github.com/gitleaks/gitleaks

Adding another check/test to our pre-commit framework.

gitleaks is a popular tool that helps with security.

Removes the gitleaks check from the Super-Linter.

So now we can run gitleaks with pre-commit on `git commit`
