Update extract_installbuilder.osx to support mac sequoia

installerbuilder.sh fails to work on macOS where /bin/sh is configured to point to a true Bourne shell. It can also fail when the it is pointed to shells like dash, Hence, change the shebang to pick the bash from environment instead of fixed path
