Fix 'Cannot find module eventsource' error in Electron.NET

Patch the bundled @microsoft/signalr v8.0.7 signalr.min.js to force
the isNode getter to return false. The universal SignalR client detects
Electron's renderer process as Node.js (via process.release.name) and
unconditionally calls require('eventsource'), require('ws'), and other
Node-only modules in the HttpConnection constructor. Since SwaggerUI
always runs in a browser context, these Node.js code paths are never
needed - the browser-native WebSocket, EventSource, and fetch APIs
are used instead.
