Bubblewrap init fails with outdated User-Agent (403 Forbidden on some hosts)

**Describe the bug**
When running `bubblewrap init` on Windows 11 (64-bit) with Bubblewrap CLI v1.24.1, the tool fails to fetch the Web Manifest from certain hosts (e.g. Netsons) because the HTTP requests use an outdated User-Agent string. The server rejects the request with `403 Forbidden`.

Steps to reproduce the behavior:

1. Run: bubblewrap init --manifest=https://tuner.netsons.org/manifest.webmanifest
