feat: merge Ready and EventEmitter (#5)

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

- **New Features**
	- Added support for Node.js version 22 in CI workflows.
- Introduced a new `ReadyEventEmitter` class for event-driven readiness
handling.
	- Added `ReadyEventClass` to manage 'ready-event' emissions.
- Enhanced documentation with a new badge for Node.js version and a
section on `ReadyEventEmitter`.

- **Bug Fixes**
- Improved promise handling and method documentation in the `Ready`
class.

- **Chores**
- Updated dependency versions in `package.json` and removed unnecessary
dependencies.
	- Removed explicit test check during the release job in CI workflows.
