Set Vite HMR Websocket protocol

What does this merge request do and why?

When NGINX is enabled with HTTPS, we need to use the wss protocol instead of the default ws.

How to set up and validate locally

With a GDK with NGINX and HTTPS enabled, try to use Vite:

nginx:
  bin: "/usr/local/bin/nginx"
  enabled: false
  http:
    enabled: false
    port: 8080
  http2:
    enabled: false
  listen: 127.0.0.1
  ssl:
    certificate: localhost.crt
    key: localhost.key
vite:
  enabled: false
  hot_module_reloading: true
  port: 3038

1. Check out to this merge request's branch.
2. Run gdk reconfigure.
3. gdk restart nginx rails-web vite
4. Navigate to GitLab and check the browser for wss requests.
