fix(app-shell): fix electron-updater failures

[mjhuff]

Overview

In #17010, we lifted electron-updater out of several package.jsons into the monorepo package.json. So yeah...electron-builder builds using the sibling package.json, because of course, it can't really know what else it needs to pull into the build from any other package.json. Woops.

This PR effectively reverts that one commit in the linked PR.

Test Plan and Hands on Testing

• Build locally (ex make -C app-shell dist-macos-latest). The build will still fail due to key signing, but the build will actually run.

Changelog

• Fixed builds failing due to "Electron Updater" errors.

Risk assessment

low

Ah, yes, sorry I didn't see this.

One interesting thing to note is that the ODD does not actually need this because it does not update itself, it only updates the robot. But it may be worth keeping just for the power of similarity.
