[CI:DOCS] push/pull docs: clarify supported transports
The man pages of podman push/pull were incomplete in explaining all supported transports. To keep things simple, explain the defaults, refer to containers-transports(5) and give some examples. Fixes: #10730 Signed-off-by: Valentin Rothberg <rothberg@redhat.com>
