[BUG] extra-args aren't passed to the "podman image exists" or "podman manifest exists"

Version

redhat-actions/push-to-registry@v2

Describe the bug

We're running redhat-actions/buildah-build@v2 rootless, which means we're using vfs and not fuse.

However when I put those options into extra-args, like:

extra-args: |
  --storage-driver=vfs
  --storage-opt=''

It still tries to use overlay options and doesn't seem to pick up --storage-driver

Steps to reproduce, workflow links, screenshots

I can't paste code outside of the emu, but this should be sufficient to replicate the problem.
