Not able to deploy package to an external registry with self signed cert

[rishi-anand]

Context

We are trying to leverage an external registry that has a self-signed certificate while deploying package via zarf

Environment

Device and OS: MacOS, Ubuntu22.04
App version: 0.23.0
Kubernetes distro being used:
Other:

Steps to reproduce

1. Zarf init using an external registry zarf init --registry-push-password=abcd --registry-push-username=abcd --registry-url=abcd.registry.local and abcd.registry.local is a local registry with the self-signed certificate.
2. Zarf init gets executed successfully
3. Run zarf package deploy zarf-package-abc.tar.zst

Expected result

Images should get uploaded to the local registry and the package should get deployed.

Actual Result

Image upload to registry fails with below error

Additional Context

Building a zarf package using images from a self-signed registry also fails. There are open issues #561 and #1015 for creating package from self signed repo.
