Clarify usability of Zarf for other software than K8s

[Silvanoc]

Looking at the entry page of the project I got the impression that Zarf can be used to package generic software for air-gap scenarios, because K8s is not being mentioned anywhere in that page. Although it is clear to me, that the main focus is packaging K8s applications, I wonder it it can be used for other container-centric types of software.

What I am interested on is somehow packaging a docker-compose setup: docker-compose.yaml configuration file + corresponding container images.

If these non-mainstream types of packages are considered, then the documentation should be improved to announce it prominently enough. It is only for K8s applications, then probably the entry page should mention that to avoid frustration of potential users.

At least an entry in the FAQs clarifying my doubts would be meaningful IMHO.
