feat: update config and generate PokeAPI client with YAML support

This commit introduces several improvements:
- Added YAML parsing support in spec loading for remote specifications
- Updated index.ts to handle YAML-formatted OpenAPI specs
- Generated new PokeAPI client and related files using the updated generator
- Modified test-config.json to use PokeAPI's OpenAPI specification
- Removed previously generated clients for other APIs
- Enhanced spec loading to detect YAML format dynamically
