Fixes #152: Set script exit code based on request success

[stephenmuss]

This small change fixes #152 and ensures that the traceback from response.raise_for_status() is not included in the program's output.

Although the property response.ok uses raise_for_status() under the hood, the raised exception HTTPError is caught and a boolean value is returned.

Using the boolean value from ok we can determine whether to set a successful or unsuccessful exit code.

Thanks for the PR!, it looks like I need to fix up the GitHub actions to validate the PR (so far, it's resisting) - please stand by :D.

[okigan]

@stephenmuss please rebase your PR (it would be nice if GH had that feature)

[stephenmuss]

@okigan have rebased

You also need to update the unit test (search TestInnerMainMethod), should be straightforward.

To test locally, you can run tox or if you have docker installed, you can run act to mimic GitHub action checks.

@okigan I've updated the test to check for exit code and tests are passing for me locally. Thanks.

Thanks @okigan!

new build is now published on PyPI, dockerhub, and GitHub Container Registry.
Homebrew will probably self-update over the next 24 hours.

Thank you for working through this!
