@sravs-dev Thanks for the PR!

Let's verify if it works in a pack CI.
You can open a PR in some Exchange pack repo. Let's pick up Github pack, the workflow is here: https://github.com/StackStorm-Exchange/stackstorm-github/blob/master/.github/workflows/build_and_test.yaml#L13
You can open a PR changing the ref to your fork with a branch.

That should use this GH Workflow and we can verify if it works OK.

Please also sign CLA.

Changing the type from string to array here would mean we have to change the matrix definition below. There, we are using matrix.include to add one entry for the indicated python version.

The docs about matrix.include are here.: https://docs.github.com/en/actions/using-jobs/using-a-matrix-for-your-jobs#expanding-or-adding-matrix-configurations

@armab I have signed the CLA, but it still shown as pending. Could you please help?

@sravs-dev Might be because you created commits on behalf of @sravanthi-konduru github account, but signed CLA as @sravs-dev? The CLA needs to be signed from the commit owner account.
