Add support for electron and electron-vite

[ElPrudi]

Hi, it seems electron is getting a lot of love in the recent years and it's rising tremendously with new template builder like electron-vite. But it seems like knip lacks support for anything electron related, marking everything as unused because of faulty entrypoints. It would be great, if you could add some support for it!

Perhaps you could shed some light on a few things:

• Any projects out there already using Knip in an Electron project? E.g. if it's just missing entry points and/or handling a bit of Electron config it could be a plugin, in which case this request should be added to Request new plugins here #483.
• Do you think/know about problematic areas such as custom module resolution? React Native has some challenges in this area (i.e. requires quite some work/maintenance), which ultimately led to abandoning Platform-specific extensions​ #126.
• Perhaps got some links to relevant docs?
• Anything else?
