When attempting to use the remote SSH installation feature by passing a user@host argument to the install script, the installation fails due to an invalid URL (https://coder.dev/install.sh) being used in the script.

This results in curl: (22) The requested URL returned error: 404 error, preventing the remote installation process from proceeding. The issue affects the ability to install the software remotely on a target machine via SSH.

Steps to Reproduce:

Run the install script with a valid SSH user and host (e.g., ./install.sh user@host).
Observe the 404 error caused by the invalid URL.
Expected Behavior: The script should reference a valid URL, allowing the remote installation to proceed without errors.

Suggested Fix: Update the script to point to the correct URL for the installation script
