The WebSocket connection fails with host 0.0.0.0

Is your feature request related to a problem? Please describe

In Development, the web socket connection expects to work with localhost but it fails with 0.0.0.0.

http://0.0.0.0:3000/	http://localhost:3000/

Describe the solution you'd like

Maybe the module could work easily with other hosts. TBH, I didn't try custom local domains with Nuxt content. I tried to map 0.0.0.0 to localhost in my /etc/hosts file, but it also fails. I guess, it just tries to connect with localhost and it cannot be changed...

Describe alternatives you've considered

• Maybe if the connection errors, we could show a more helpful error message in the browser console too.
• The module could expose the host as an option to configure, and it should be documented

Additional context

It seems like wsUrl is an option in the module, but I couldn’t find it in the docs or if it's configurable.

Try setting this in you nuxt.config

content: {
    watch: {
      hostname: '0.0.0.0',
      ws: {
        serverOptions: {
          host: '0.0.0.0',
        }
      }
    }
  },

This options are described in https://github.com/unjs/listhen?tab=readme-ov-file#options

Just to know, which approach you took to change Nuxt host to 0.0.0.0. I'm thinking maybe Nuxt Content could detect the custom defined host and automatically update this config 🤔
