Remove bugsnag error tracking from codebase

[Copilot]

Completely removed bugsnag error tracking from the project.

Changes

• Removed bugsnag integration: Removed all bugsnag imports and initialization from modules/gob-web/analytics.js
• Removed dependency: Removed @bugsnag/js package from modules/gob-web/package.json
• Removed type definitions: Deleted flow-typed/npm/bugsnag-js_vx.x.x.js stub file
• Updated lock file: Removed all bugsnag-related packages from package-lock.json

 // @flow
-import Bugsnag from "@bugsnag/js"
-const BUGSNAG_KEY = "7e393deddaeb885f5b140b4320ecef6b"

 export default function start() {
   if (process.env.NODE_ENV === "production") {
     console.log("Initializing analytics 📊")
     isogram()
-    Bugsnag.start({ apiKey: BUGSNAG_KEY })
   }
 }

The application now uses only Google Analytics for tracking. As a bonus, the bundle size decreased by 47 KiB.

Testing

• ✅ All tests pass (561 tests)
• ✅ Linting passes
• ✅ Flow type checking passes
• ✅ Build succeeds
• ✅ No bugsnag references remain in codebase

Fixes #2404

This section details on the original issue you should resolve

<issue_title>Dependency deprecation warning: bugsnag-js (npm)</issue_title>
<issue_description>On registry https://registry.npmjs.org/, the "latest" version (v4.7.3) of dependency bugsnag-js has the following deprecation notice:

All projects should upgrade to our universal JS notifier: "@bugsnag/js". See https://github.com/bugsnag/bugsnag-js/blob/master/UPGRADING.md for more details.

Marking the latest version of an npm package as deprecated results in the entire package being considered deprecated, so contact the package author you think this is a mistake.

Affected package file(s): modules/gob-web/package.json

If you don't care about this, you can close this issue and not be warned about bugsnag-js's deprecation again. If you would like to completely disable all future deprecation warnings then add the following to your config:

"suppressNotifications": ["deprecationWarningIssues"]
