Add default plural rules
This makes the PO loader correctly handle the situation where the optional `Plural-Forms` header field does not exist. The `Translation` class and its subclasses always have access to valid plural rules via `_get_plural_rules()`. Plural rules are prioritized: 1. `Translation.plural_rules_override` 2. `TranslationServer.get_plural_rules(locale)` 3. The English plural rules: `nplurals=2; plurals=(n != 1)` Co-Authored-By: Pāvels Nadtočajevs <7645683+bruvzg@users.noreply.github.com>
