🎨 Multilingual site features

Language switching

Language selection displayed in header:``` 🌐 日本語 | English

Clicking will automatically switch to the corresponding language page.

### Search function

**Search in both languages:**
- Search in Japanese → Search for Japanese documents
- Search in English → Search for English documents
- Improve accuracy with morphological analysis and stemming

### URL scheme

**Japanese version:**```
https://evospikenet.readthedocs.io/
https://evospikenet.readthedocs.io/overview/
https://evospikenet.readthedocs.io/getting-started/quickstart/

English version:``` https://evospikenet.readthedocs.io/en/ https://evospikenet.readthedocs.io/en/overview/ https://evospikenet.readthedocs.io/en/getting-started/quickstart/

*.en.md files are automatically served in the /en/ path

- [ ] faq.en.md - FAQ
- [ ] getting-started/installation.en.md - Installation
- [ ] getting-started/first_simulation.en.md - First simulation

Estimated working time: 6-8 hours

### Phase 3: Reference

Priority: **Medium**

- [ ] reference/api_reference.en.md
- [ ] reference/module_reference.en.md
- [ ] reference/configuration.en.md
