Describe the bug
i installed pulse on a new Proxmox VE 9.1 server using the recommended method (quick install, no auto update, no sensors)
i can see in Proxmox network usage diagram that every 5 Minutes 3 MB of data are downloaded

Reason is the selfcheck. It downloads automatically the newest beta version, even when auto update is DISABLED and update channel = "stable"

To Reproduce
Steps to reproduce the behavior:

1. install Proxmox VE (i tested with: 9.1-1)
2. install Pulse LXC Container (tested with 4.36.2 - ): curl -fsSL https://github.com/rcourtman/Pulse/releases/latest/download/install.sh | bash
3. quick install, no auto update, no sensors
4. do user setup in pulse (get setup_token, create admin user)
5. install sensors curl -fsSL https://github.com/rcourtman/Pulse/releases/latest/download/install-sensor-proxy.sh | bash -s -- --ctid 101
6. now - every time when systemd timer "pulse-sensor-proxy-selfheal.timer" triggers, the entire pulse 5.0.0-rc.1 is downloaded! every 5 minutes -> 11 GB every day!
   Call Stack:

• /bin/bash /opt/pulse/sensor-proxy/bin/pulse-sensor-proxy-selfheal.sh
• bash /opt/pulse/sensor-proxy/install-sensor-proxy.sh --ctid 102 --skip-restart --quiet
• curl --fail --silent --location --connect-timeout 10 --max-time 240 https://github.com/rcourtman/Pulse/releases/download/v5.0.0-rc.1/pulse-v5.0.0-rc.1-linux-amd64.tar.gz -o /tmp/tmp.BoiyZjUQTa

Workaround (not recommended)
systemctl disable pulse-sensor-proxy-selfheal.timer

Expected behavior
new version is downloaded only when needed and only using the defined update channel

Environment:

• Pulse Version: v4.36.2
• Installation Type: ProxmoxVE LXC
