running script_checks with no docker, Node.js Deployment

[ignoramous]

I am not sure how buildpacks work, but try some / all of these:

1. The script is missing exec permissions, so modify: chmod +x ./health_check.sh
2. Remove the shebang #!/bin/bash from health_check.sh 'cause bash may not be at /bin?
3. Remove bash from [[services.script_checks]] command (ref).
