The default zone of firewalld used by podman is not trusted

### Feature request description

For quite some time, the firewalld zone used by podman was trusted, but this behavior ran into some frustration when I tried to use trusted for its original purpose.

### Suggest potential solution

When dealing with firewalld, start by creating a separate zone, such as "podman".

### Have you considered any alternatives?

idk

### Additional context

docker does not use trusted, but creates a docker zone for itself.
