podman buildx build is missing --push flag

[uhthomas]

Issue Description

I've just installed podman on Arch Linux with podman-docker and I'm unable to build an open source project because the buildx API is missing the --push flag.

Error: unknown flag: --push
See 'podman buildx build --help'

I found containers/podman#17339, which was closed? The author claimed they would make another issue, but I can't find it if it exists.

Steps to reproduce the issue

Steps to reproduce the issue:

1. podman buildx build --push

Describe the results you received

Error: unknown flag: --push
See 'podman buildx build --help'

Describe the results you expected

A successful build and push.
