ESM example/usage

[rtritto]

With ESM, the electron-squirrel-startup dependency can't be found if it's in dependencies (it works if I move it into devDependencies):

• require.resolve (Node < 20.6.0) example; src/main.ts file:

  import { createRequire } from 'node:module'
  import { fileURLToPath } from 'node:url'
  
  const require = createRequire(import.meta.url)
  const __dirname = path.dirname(fileURLToPath(import.meta.url))
  
  try {
    // Handle creating/removing shortcuts on Windows when installing/uninstalling.
    require.resolve('electron-squirrel-startup/package.json')
    // OR require.resolve('electron-squirrel-startup/package.json', { paths: [__dirname] })
    app.quit()
  } catch (error) {
    // Ignore
    console.log('Ignore error: ', error)
  }
  

  Console output:

    Ignore error:  Error: Cannot find module 'electron-squirrel-startup/package.json'

      code: 'MODULE_NOT_FOUND',
      requireStack: [ 'C:\\template-electron-vite\\.vite\\build\\main.js' ]
    }
  

• import.meta.resolve (Node.js >= 20.6.0) example; src/main.ts file:

  try {
    // Handle creating/removing shortcuts on Windows when installing/uninstalling.
    import.meta.resolve('electron-squirrel-startup/package.json')
    app.quit()
  } catch (error) {
    // Ignore
    console.log('Ignore error: ', error)
  }
  

  Console output:

  }
  

Note: an example for ESM use case should be added in README.md.
