Overriding WDS_SOCKET_PORT in .env doesn't update hot-update.json port

[jairmedeiros]

I have a larger .NET MVC application running the application on port 58778, and on a subdir I have .NET serve html page with a script tag referencing some bundles loaded from create-react-app

    <script src="http://localhost:3000/financials/static/js/bundle.js"></script>
    <script src="http://localhost:3000/financials/static/js/0.chunk.js"></script>
    <script src="http://localhost:3000/financials/static/js/main.chunk.js"></script>

It loads the app fine initially, but subsequent hot reloads don't seem to go through, been tracking this PR #7750 and it seems like using overriding WDS_SOCKET_PORT would have that worked, but I'm still seeing http://localhost:58778/financials/1040a39746f45ba56ee1.hot-update.json 404 (Not Found).

I would think setting the WDS_SOCKET_PORT would have this resolve properly.

my .env

PORT="3000"
WDS_SOCKET_PORT="3000"

How about setting it as WDS_SOCKET_PORT=0? I tried on my React app and it seems working.
