Robust fix needed for non-interactive cloudfront-auth

The main issue is that the cloudfront-auth repo code is interactive only, doesn't support non-interactive CLI usage or loading all settings from a preconfigured file.

The tool we are using to build the CloudFront authentication lambda (https://github.com/Widen/cloudfront-auth) - Connect to preview only supports interactive mode. Even with a saved out configuration file, it continues to interactively prompt — it just uses the saved configuration for the prompt defaults. This does not lend itself to automation.
However, I was able to add a single line of code to enable command line-based automation for our use case. That's how this action is currently working -- it is patching in that line prior to run. But we're going to need something more robust/less hackish.

Options:
* PR to Widen/cloudfront-auth ?
* Fork Widen/cloudfront-auth ?

I noticed there's already a PR dated Mar 1 in Widen/cloudfront-auth to address our use case and more (https://github.com/Widen/cloudfront-auth/pull/84). But it's much more than a one-line change. If that gets merged that will resolve our issues. Just not sure when that'll happen.

**Rob has suggested either:**

* I suggest fork and apply the pull request(84), and then track and revert to main when fixed.
* Also fine with leaving with your patch for now, if arkadiy reviews.
