docs: document preview support for systemd

[jason-lynch]

Summary

Adds a page to our docs that describes the preview support for systemd using the RPM files attached to our releases.

Testing

Create a test release with:

make goreleaser-test-release

Then, start one or more VMs using the template in the lima directory, e.g.:

limactl start -y --name=rpm-test-1 lima/lima-template.yaml

Now, when you connect to the new machine, you'll find that your home directory is mounted inside the VM. The path will change depending on where the control plane repo is on your host machine, the VM architecture, and the specific git commit that you've built, but in general the installation should look like:

# connect to the machine
limactl shell rpm-test-1

sudo su -

rpm -i /Users/jasonlynch/workspace/pgEdge/control-plane/dist/pgedge-control-plane_0.6.2-SNAPSHOT-a8765012_linux_amd64.rpm

# Or to upgrade an existing installation
rpm -U /Users/jasonlynch/workspace/pgEdge/control-plane/dist/pgedge-control-plane_0.6.2-SNAPSHOT-a8765012_linux_amd64.rpm

From there, you can follow the other instructions in the doc to install prerequisites, configure, and start the control plane.
