Steps to Reproduce:

1. Clone https://github.com/home-assistant/core

2. Include portAttributes to the devcontainer.json:

   {
     "appPort": ["8123:8123"], // existing
     "portsAttributes": {
       "8123": {
         "label": "Home Assistant",
         "onAutoForward": "silent"
       }
     }
   }

3. Reopen in the devcontainer

4. Check ports tab:

1. Proposal: support forwarding UDP ports devcontainers/spec#643
2. https://github.com/home-assistant/core/pull/154099/files#r2417724273
