Problem: getting parseable list of packages

Currently this would require some scripting.

Solution: add `-f json` option to `pgpm search`

While at it, make sure Podman doesn't print on stdout to avoid messing up JSON
output.

Also, improve search printing a bit by printing search result in progress.
