Motivation, issues

orb-tools/check-env-var-param command doesn't properly work at the current orb version, and it doesn't ensure all the environment variables exist. This issue has fixed in a newer version. So I'll update orb-tools version 8.26.0 to 9.3.1, so the following PR has applied and fixed the issue.

Description

Here is the test to confirm the newer verison of orb-tools ensure all the environment valiables exist.

[gmemstr]

This orb is due a rework, but I think this upgrade is good to at least bring it inline with the CircleCI config.
