Is your feature request related to a problem? Please describe.

It is very unclear when working with different init packages, say one for a single node cluster and one for a multi-node cluster, to have them both be called zarf-init-vX.X.X-amd64.tar.zst.

Describe the behavior you'd like

• Given a .metadata.name of not init (for backwards compatibility with the main init package).
• Then the .metadata.name is appended to the local tar-bundle, such as zarf-init-single-vX.X.X-amd64.tar.zst

Describe alternatives you've considered

After pulling one zarf init package to manually rename it on disk, then pull the second init package.
