[forge-*] Add missing @electron-forge/plugin-auto-unpack-natives plugin config

[rtritto]

@electron-forge/plugin-auto-unpack-natives is included as dependency in package.json but it's not used in forge.config.cts.

Change

forge.config.cts:

• forge-esm-ts
• forge-esm
• forge-svelte

const config: ForgeConfig = {
  plugins: [
    new VitePlugin({
      ...
    }),
+    {
+      name: '@electron-forge/plugin-auto-unpack-natives',
+      config: {}
+    },
    new FusesPlugin({
      ...
    })
  ]
}
