Subject: [PATCH 1/2] fix(ext): update TypeScript templates for ext:dev:init

The default TypeScript extension template generated by `firebase ext:dev:init` was failing to build due to outdated dependencies and TypeScript configuration.

This commit updates the templates to:
- Bump the TypeScript version to `^5.3.0` in `package.json`.
- Add `"skipLibCheck": true` to `tsconfig.json`.
- Change the `firebase-functions` import to `firebase-functions/v1`.

These changes ensure that newly generated TypeScript extensions build successfully without any errors.
