[REQUIRED] Describe your environment

• Operating System version: macOS 13.3.1 (a)
• Browser version: Google Chrome 113.0.5672.63
• Firebase SDK version: 9.21.0
• Firebase Product: sdk (auth, database, storage, etc)

[REQUIRED] Describe the problem

With the new "moduleResolution": "bundler" mode of TypeScript 5.0+, TypeScript errors on attempting to access any type from the firebase global namespace with firebase/compat/app and friends imported. It works with "moduleResolution": "node".

Steps to reproduce:

1. Clone https://github.com/segevfiner/firebase-types-issue
2. pnpm i
3. pnpm type-check.
4. If you set "moduleResolution": "node" in tsconfig.app.json it will work, but it should work with the new moduleResolution mode as well.
