Configurable Default Electron Port

In many environments developers are not permitted to find available port. We must use specified ports allotted. Can we change the main.js file to include the following (~ line 66):

    let defaultElectronPort = 8000;
    if (manifestJsonFile.electronPort) {
        defaultElectronPort = (manifestJsonFile.aspCoreBackendPort)
    } 
    // hostname needs to belocalhost, otherwise Windows Firewall will be triggered.
    portscanner.findAPortNotInUse(defaultElectronPort, 65535, 'localhost', function (error, port) {
        console.log('Electron Socket IO Port: ' + port);
        startSocketApiBridge(port);
    });

This will allow users to explicitly set the port just as you can do with the aspNetCore port.

I put in the PR. Let me know if it is wrong.

Is there some guidance on the electron.manifest.json “files” section? I think I can work around this problem by making my own main.js but I can’t find any docs on how it works and copying an example ElectronHostHook does seem to overwrite the main.js.
