Add .metro-health-check to .gitignore

Summary: Changelog: [General][Changed] - Add Metro health check files to the template's `.gitignore` We're adding an opt-in watcher health check to Metro, which can occasionally leave files named `.metro-health-check*` in the project. To ensure this doesn't clutter people's repos accidentally if enabled, we preemptively add this as a pattern to `.gitignore` in the new project template. We also add it to the React Native repo's `.gitignore` file just in case. Reviewed By: arushikesarwani94 Differential Revision: D40352040 fbshipit-source-id: 261803b684d79292c014205084e61d5e4f7aeb3d
