Summary: Addresses an issue where on macOS, we briefly flashed the RNDT app icon in the Dock. (This has been raised to us recently by Expo.) **More info** The `unstable_prepareDebuggerShell` health check was spawning the Electron binary with `--version` after a successful `dotslash fetch`. Invoking the native binary causes the app icon flash. - I couldn't find an Electron-side way to eliminate this (e.g. headless). - DotSlash already performs mandatory verification of every fetched artifact. The additional `--version` spawn was therefore redundant/overkill. Changelog: [General][Fixed] - React Native DevTools will no longer briefly flash in the system dock/taskbar when starting Metro Differential Revision: D104061238
