refactor(examples): latest electron-forge and typescript configs

[jjeff]

This PR updates the modules in examples/electron-forge-typescript-webpack. This means moving from beta Electron Forge to release 6, which changes the configuration files some. I also updated all of the config files to Typescript, and included the webpack.preload.config file in the configuration.

This all works fine on the Mac.

HOWEVER, on Windows, there's currently a bug in either Electron Forge, Bytenode Webpack Plugin, or Bytenode which generates the following error when launching:

The full error is

SyntaxError: Cannot use import statement outside a module
    at Object.compileFunction (node:vm:360:18)
    at wrapSafe (node:internal/modules/cjs/loader:1062:15)
    at Module._compile (node:internal/modules/cjs/loader:1097:27)

Further examination: The line linked in the error (line 368 of main.js) contains the following:

"use strict";
module.exports = require("C:\\Users\\jeff\\OneDrive\\Documents\\Code\\bytenode-webpack-plugin\\examples\\electron-forge-typescript-webpack\\src\\index.ts");

It looks like the original typescript file is being required here rather than the .jsc file.

..and on Mac, this same line reads:

"use strict";
module.exports = require("./main.compiled.jsc");

Hoping to look into it this weekend
