[CI:DOCS] fix default branch links

* Replace https://github.com/containers/podman/blob/master
  with https://github.com/containers/podman/blob/main
  to match the new default branch "main". Previously
  the default branch was "master". The substitutions were
  made in the documentation but not the code.

 Some of these restrictions can be lifted (via `--privileged`, for example), but rootless containers will never have more privileges than the user that launched them.
 If you run Podman as your user and mount in `/etc/passwd` from the host, you still won't be able to change it, since your user doesn't have permission to do so.

 The remote client takes advantage of a client-server model. You need Podman installed on a Linux machine or VM that also has the SSH daemon running. On the local operating system, when you execute a Podman command, Podman connects to the server via SSH. It then connects to the Podman service by using systemd socket activation, and hitting our [Rest API](https://docs.podman.io/en/latest/_static/api.html). The Podman commands are executed on the server. From the client's point of view, it seems like Podman runs locally.
