additional_components null resource exists with not found - wrong shebang

TL;DR

The null resource for additional components uses a local-exec provider. This means, the executed command will be something like bin/sh -c <command>.
The script scripts/check_components.sh contains the shebang line #!/bin/bash. Running on images without a bash, but with a sh (like basic alpine images), the command will fail.

Expected behavior

The command script will be exectuted successfully.

Observed behavior

The script exits with exit code 127 - command not found

Would it be possible to cut a release to bring this change into a tagged version? Other google-hosted modules call this module with a version = "~> 3.1" version constraint, and so it's not possible to bring this change in until a new release is cut.
