feat: don't generate typings/config/index.d.ts on egg >= 4.0.0 (#118)

<!-- This is an auto-generated comment: release notes by coderabbit.ai
-->

## Summary by CodeRabbit

- New Features
- Automatically detects framework version and propagates it through
configuration.
- Skips generating config typings when using Egg 4.x+ to prevent
incorrect outputs.

- Chores
  - Updated development dependency version of Egg.

- Tests
  - Added tests ensuring no config typings are generated for Egg 4.x+.
- Re-enabled esm-app tests with focused assertions on controller and
context typings.
