Fix CVE-2026-25896: Upgrade deep transitive dependency fast-xml-parser from 4.5.0 to 4.5.4

## Summary
Upgrading the deep transitive dependency `fast-xml-parser` from 4.5.0 to 4.5.4 in `xplat/js/react-native-github` to fix:
- CVE-2026-25896 (Incorrect Regular Expression)

Dependency chain (3 levels deep):
  react-native/tester -> react-native-community/cli-platform-android -> react-native-community/cli-config-android -> fast-xml-parser@^4.4.1

The semver range `^4.4.1` naturally allows 4.5.4, so the version was nudged via temporary resolution and sticks after removal. No permanent resolution needed.

Changelog:
[General][Security] - Bumped fast-xml-parser from 4.5.0 to 4.5.4 to fix CVE-2026-25896
