Provide quadlet Instructions for Installing Supabase

[phreed]

When running Supabase as a daemon service there are a few options.
One way would be under the control of systemd as a podman quadlet.
I am developing such documentation based on the docker install documentation.
The problem with such a strictly docker based install is that it deviates from the standard system service control.

If you are interested I can provide a pull-request,
in any case I have attached a zip with the quadlets and scripts I have been using.

I have not yet enabled the systemd-creds for this.
It will be something like...

[Unit]
Description=My App with Secrets
LoadCredentialEncrypted=db-password:%h/secrets/db-pass.cred

[Container]
Image=my-app-image
Volume=%d:/secrets
Exec=/usr/bin/myapp --password-file=/secrets/db-pass.cred

Or, via podman secrets.
