[CI:DOCS] podman cp: highlight globbing and multi-file copy 

`podman cp` does not allow for globbing or filtering copied data in any
form.  `docker cp` does not either, so Podman remains compatible.  Due
to a number of requests, highlight how users can effectively achieve
that by means of chaining with tools such as xargs(1) or find(1), or by
making use of `podman mount`.

@ -52,6 +52,8 @@ Using `-` as the **src_path** streams the contents of `STDIN` as a tar archive.
Note that `podman cp` ignores permission errors when copying from a running rootless container. The TTY devices inside a rootless container are owned by the host's root user and hence cannot be read inside the container's user namespace.
Further note that `podman cp` does not support globbing (e.g., `cp dir/*.txt`). If you want to copy multiple files from the host to the container you may use xargs(1) or find(1) (or similar tools for chaining commands) in conjunction with `podman cp`. If you want to copy multiple files from the container to the host, you may use `podman mount CONTAINER` and operate on the returned mount point instead (see ALTERNATIVES below).
