fix: Update kubectl-kui location on macOS to Kui.app/Contents/Resources

This change is suggested because I'm submitting a Cask to Homebrew and would like to include the kubectl-kui binary in /usr/local/bin directly while installing the application to /Applications. Additionally, I ran by habit "kubectl kui get pods" from inside Kui and it appeared to hang indefinitely. This script prevents that, though it doesn't produce pretty output like Kui normally would.
